The difference between esp and esc is: 1. Different names: ESP is Bosch's patented body electronic stability system, which improves the stability of the vehicle in extreme situations by limiting engine power and independent wheel braking. Rescue the vehicle when the driver takes dangerous actions. esc is a common name. Since Bosch registered the ESP patent, non-Bosch system car manufacturers had to invent this name. For example, Toyota calls it SC vs. Porsche calls it PSM. 2. Introduction to ESC: The basic function of the ESC module itself is to control the hydraulic circuit of the vehicle braking system to distribute braking force and adjust torque to the wheels. So basically all the functions related to torque and braking force can be realized. It's just a matter of complexity or not.
