Moose test
"Elk test" is an important index to measure the emergency obstacle avoidance performance of vehicles in the world. Engineers carefully calibrated and tested the steering, suspension system and tires of the vehicle. "Elk test" has a very severe test on the center of gravity and suspension of vehicles.
In the elk test, Rick zero? The concept production car shows extremely accurate steering, and the directivity and tracking performance of the car are excellent in the whole process. The maximum speed passed the elk test is over 80km/h, which has reached the level of high-performance sports car.
Tracking test
Track driving will mainly test the acceleration/braking performance of the vehicle and the handling stability of the steering/chassis. On the track, engineers will test the zero point? The comprehensive acceleration and braking performance of the concept production car is reported to be zero? The 100-kilometer acceleration time of the concept production car will be less than 4 seconds.
At the same time, the extreme attitude and passing speed of vehicles in various high-speed and low-speed corners on the track are also the focus of engineers' testing on the track. Through a series of dynamic tests, engineers will continue to optimize zero? The technical details such as suspension stiffness and steering gear ratio of the concept production car have improved the dynamic performance of the whole car and laid a solid foundation for driving pleasure.
Review: zero? Release of concentrate
On September 23rd, on the eve of the opening of Beijing Auto Show, Nianlida took the lead in holding a press conference to officially release its first pure electric platform? Sea? Broad platform and the first pure electric vehicle-Zero? Concpet？ .
Construction of pure electric exclusive platform
According to the information at the press conference, there are more than 7 brands based on the vast architecture, totaling more than? 16? A new model began to be developed and different market segments were laid out. According to the plan, starting from 202 1, a number of new models based on the vast architecture will be put on the market one after another.
202 1 introduced the first pure electric vehicle. I have to say that this progress has fallen far behind many competitors. Since the speed is not comparable, then the technology must have a bright spot.
Characteristics of huge buildings
I. Spatial structure
The broad architecture realizes the wheelbase range from 1800 mm to 3300 mm, covering all specifications of A-class cars to E-class cars. Including cars, SUVs, MPVs, station wagons, sports cars, pickup trucks and other body shapes.
The second and third power systems
The vast architecture adopts the new three-electricity concept of electric drive, electric tube and electric ecology, and is known as a 200,000-kilometer long-life power battery with no attenuation and 2 million kilometers under NEDC working conditions.
Among them, 1 10kWh modular CTP integrated battery pack has a cruising range of more than 700 kilometers. A single motor can achieve the maximum power output of 475kW, and it is equipped with a self-developed high-performance two-speed electric drive transmission, and the maximum wheel end load torque can reach 8000Nm.
In terms of charging speed, the maximum 800-volt high-voltage system that can be carried can realize charging for 5 minutes and battery life 120 km.
Third, support FOTA with full scene and full life cycle.
Start sailing? OS vehicle intelligent development system, based on the integration of three domains into the central integrated electronic and electrical architecture, forms a complete development system through software and hardware, software algorithms, cloud computing and application scenarios. Its core chip components will be independently developed in the future. At present, more than 4,000 API interfaces have been implemented, which can realize FOTA in the whole scene and life cycle.
Fourth, fully automatic driving of open roads will be realized in 2025.
The vast architecture adopts the technical route of advanced assisted driving, highly automatic driving and fully automatic driving, and has the ability to meet fully automatic driving, and can realize the automatic driving functions of getting rid of hands, leaving eyes, autonomous parking, automatic lane change and automatic navigation.
Personal vehicles based on the vast architecture will realize high automatic driving on structured roads in 20021year. Before 2023, open roads will achieve a high degree of automatic driving. At the same time, intelligent vehicles such as self-driving taxis developed on vast structures will take the lead in fully automatic driving on structural roads in 2022, and provide intelligent travel services in the core area of the 2022 Asian Games; By 2025, open roads will realize fully automatic driving.
Verb (the abbreviation of verb) has a performance of 50:50 weight distribution, and the fastest acceleration of 100 kilometers is less than 3 seconds.
The vast architecture takes the battery as the center and adopts the exclusive high-performance pure electric chassis, which not only has a low center of gravity, but also can balance the front and rear weights by 50:50. The products on the architecture can be equipped with a high-performance electric four-wheel drive system and a dual-motor layout with a maximum of 600kW, shortening the acceleration time of the products to less than 3 seconds.
After reading the description of this pure electric platform in the press conference, we can see that the key elements of new energy are ready, including battery life, charging speed, performance, autonomous driving and OTA capability of the whole vehicle. When these conditions are basically met, new energy vehicles will jump out of the category of traditional fuel vehicles. So what is the performance of the first pure electric vehicle based on the vast platform? Let's take a look at the real car.
-ZERO, the first pure electric vehicle based on the vast platform? Kompet
Let's take a quick look at its basic information:
1, zero Concept positioning pure electric luxury coupe, with a length of nearly 5 meters and a wheelbase of 3 meters.
2.NEDC has a battery life of more than 700km, the acceleration of 100 km is less than 4 seconds, and the test score of Elk exceeds 80 km/h. ..
3. It has fully automatic driving ability and can provide FOTA with full scene and full cycle.
4. The official listing time is 202 1 the second half of the year.
You can see, zero? The whole appearance of concept continues the family-style design elements of Lectra, such as the iconic split light group and the penetrating front face shape, which are all very familiar elements.
The difference is that as a pure electric vehicle, it adopts a closed front face. The previous air intake grille disappeared and was replaced by a black piano paint decoration, which formed a transparent visual effect with the headlights.
Headlamp group uses arranged LED light sources. The combination of these design elements makes the whole front face still have a layered feeling similar to that of a fuel car. The whole front face is not subversive enough, but the momentum is still enough.
The side of the car body can be said to be the highlight of the car. The C-pillar with huge inclination makes this car full of cross-border flavor. The concept car has a length, width and height of 4850/ 1980/ 1530mm, and a wheelbase of 2999mm, which is already the standard for medium and large cars.
The design of the wheel hub is also very eye-catching. The rim size of the two-color cyclone wheel has reached 22 inches, and the tires are equipped with 265/40? R22 continental tire.
In addition, the concept car is also equipped with induction electric doors with frameless design, automatic air suspension and hidden door handles.
The taillights of the concept car are highly recognizable and adopt a through design style. But in addition to the main light sources on both sides, four LED light-emitting units are used as a group to arrange multiple groups of light sources. In addition, the car is equipped with a very sporty rear spoiler.
As for the interior, this conference has not been announced, but according to the previous spy photos, the central control operation area is inclined to the driver's side, and the floating large screen design is adopted, and in addition to the small electronic gear handle, the central control and central channel in the car also cancel most physical buttons.
In terms of power, the new car will be equipped with a power battery pack with a capacity of 1 10kWh. According to the comprehensive power consumption (13.8-15.7kwh/100km) published by the EIA data of the new car, its cruising range may be around 637-725km. As for the earliest time for mass production, according to the information of the press conference, it will be in the second half of 20021year at the earliest.
