"Three Machines and Four Wheels" Power System
In today's article, we should start with the power of this Tianyi PHEV. Its power consists of three parts: engine, front drive motor and rear drive motor.
Engine equipment 1.6T? PHEV exclusive high-power engine, the maximum power 147kW, the maximum torque of 300Nm, the power level is equivalent to the mainstream 2.0T engine. Using a larger turbine instead of a small inertia turbine to enhance the dynamic performance of the engine in the middle and high speed range can better achieve the balance between power and economy.
The front motor adopts the mainstream permanent magnet synchronous motor, matching the industry-leading flat wire and oil cooling technology, with high power density and better efficiency. The front motor has a peak power of 8 1kW and a peak torque of 320Nm.
The rear motor is the mainstream permanent magnet synchronous motor with the highest speed of 14000RPM. The peak power of the rear motor is 83kW, and the peak torque is 166Nm.
The hybrid system composed of these three parts has a comprehensive maximum power of 22 1kW and a comprehensive maximum torque of 520Nm. The official acceleration time of 100 kilometers is 7s.
The gearbox of this car is equipped with E-ATN8 electric automatic gearbox, which is rare in the same class. It integrates front motor and gearbox, which improves driving comfort.
"P0+P2+P4" Three-motor Architecture
The motor architecture of P0+P2+P4 adopted by Tianyi PHEV is also one of its advantages. Compared with the P0+P4 structure of general plug-in hybrid vehicle, the extra P2 of PHEV enables it to cope with different driving conditions in a more ideal working condition. First, let's look at the functions of these three parts of the motor architecture.
First of all, P0 motor is what we often call BSG- belt starter generator, and it is also the basic mechanism of hybrid electric vehicle, including 48V optical hybrid system. It can effectively avoid the vibration impact caused by the front motor driving the vehicle and starting the engine at the same time, eliminate the risk caused by the motor driving the vehicle and starting the engine at the same time when the power battery is insufficient, and also reduce the starting noise of the traditional starter.
P2 front motor is integrated into ATN8 gearbox of Aisin to form an eight-speed electric automatic gearbox of e-ATN8. It can realize pure electric drive, hybrid drive with engine, and also play the role of generator, or charge the power battery, or provide electric energy for the rear motor to drive the vehicle, and also recover braking energy.
The rear axle is matched with the P4 frame motor built in the three-in-one electric drive assembly. It can drive the vehicle independently, realize pure electric four-wheel drive with the front motor and hybrid four-wheel drive with the engine, and recover braking energy.
Therefore, under the cooperative work of P2 motor, P4 motor and engine, under different modes and working conditions, the three power units sometimes work independently and sometimes work in a mixed way, forming a unique 12 working state of Tianyi PHEV.
When the four-wheel drive mode is selected for unpaved pavement, the rear motor will continue to work, and the engine and the front motor will intervene as needed to ensure the passability on unpaved pavement and achieve the best economy. In order to ensure that the rear drive motor can work continuously in the four-wheel drive mode, when the battery power is too low, the engine will forcibly intervene to charge the battery for the rear drive motor to work.
For legal brands such as Citroen, excellent chassis training has always been their proud advantage. On this Tianyi PHEV, we also experienced the well-deserved "Chassis Master Training". Its PHC adaptive hydraulic stability technology comes from WRC champion technology, which can bring better vibration filtering feeling to the occupants in the car.
Through the field test on the grassland dirt road, which is a typical bad road, Tianyi PHEV can well filter the small bumps on the road, and the big bumps can also become a softer and more comfortable feeling under the guarantee of Citroen master chassis adjustment technology, instead of the very tough feeling of going straight up and down.
Under the guarantee of three power units, there is no doubt about the acceleration ability of PHEV in Tianyi. In the hybrid mode, the motor can be started quickly at the beginning, and the power can be continuously output in the middle and late acceleration due to the * * * of the motor and the engine. So even if you overtake at high speed, you can hardly feel the lag of power.
The official 100-kilometer acceleration of this car is 7 seconds, but in our actual driving experience, we feel that the official 7-second acceleration time is a bit too conservative, and the intuitive feeling of simple acceleration should be within 7 seconds. By inquiring the actual test results of other media, the acceleration time of this Tianyi PHEV is 5.9s
The NVH performance of Tianyi PHEV is also a big surprise. Because a large number of acoustic materials are carefully arranged in the engine compartment, the noise in the engine compartment is hardly felt in the car. The front window adopts ultra-quiet front sound insulation film, which greatly increases the sound insulation effect of glass and improves the ride comfort. The sound insulation film used in the wheel cover can minimize engine noise and tire noise, and effectively isolate the noise outside the car.
For a comfortable SUV model, the adjustment of the brake pedal by Tianyi PHEV is also very linear, which gives people very strong confidence in the initial stage of stepping on the brake pedal. At the same time, it is also equipped with iBooster regenerative braking and energy recovery system, which helps to make braking more sensitive and improve the automatic emergency braking performance. At the same time, Tianyi PHEV can recover braking energy as high as 100%, and store excess kinetic energy as electric energy to improve endurance.
Design review:
The design of Tianyi PEHV continues Tianyi C5? The design language of AIRCROSS, even the design of 20 17, is still one of the most advanced designs after three years. Designers have adopted a large number of rounded rectangular designs on Tianyi PHEV, so it seems that it has such a theme spontaneously.
The overall design style of Tianyi PHEV body is soft and round. But how to express SUV with soft lines is a difficulty. If you don't play well, you will be called "sissy" or "chubby". Therefore, designers should pay special attention to highlighting the sense of car body, use rising/falling arcs to create a sense of rhythm, and also arrange some "seemingly unexpected" design elements in details.
The rear of the car continues the soft and bold French model, and the circular and rectangular design elements continue to the design of taillights. After such a taillight is lit at night, people who know it can recognize it at a glance. The exhaust pipes on both sides of the tunnel are equally serious about this design element.
At first glance, the interior is not as amazing as the appearance, and a large number of slightly square straight-line designs highlight the simple style, but if you look closely, you will find that the French have buried a lot of thoughts in the details. Although the contrast between brown, red and black is not unusual now, at least it doesn't look boring.
Summary: PHEV entered the market a little late at this stage, which seems to be not a good time for the current French cars. However, Tianyi PHEV does have many advantages. Paying attention to comfort training has always been the specialty of the French, so this has become the unique advantage of Tianyi PHEV. Master chassis training is really blown out. This kind of invisible and intangible somatosensory feeling can only be felt by test drive yourself. Excellent NVH performance is also outstanding in this class of SUV. Therefore, can Tianyi PHEV make a good start for Dongfeng Citroen in the era of electrification and achieve the goal of 100% electric version of its models in 2025? Let us look forward to its market performance.
