Passenger car control system

Yingchuang Huizhi can provide drive-by-wire chassis systems for passenger car types, including brake-by-wire systems, steering-by-wire systems and drive-by-wire systems. The brake-by-wire system mainly uses TBS, ESC and EPB to realize multiple redundant backup and precise braking solutions. The steering-by-wire system uses dual-motor safe redundant steering system as the key component, which can realize precise steering angle control. The drive-by-wire system mainly Accurate speed control is achieved by means of signal simulation.
Multiple redundant brake-by-wire system

Product advantages
  • TBS active braking + ESC backup braking + EPB backup braking + driver backup braking: constitute multiple redundant mechanisms to meet the safety requirements of autonomous driving above L3 level;
  • Electric control brake booster system TBS: semi-decoupled technical solution, with three functions of brake booster, brake-by-wire, and support for braking energy recovery, 10MPa pressure build-up time 250ms;
  • Electronic stability control system ESC: It has more than 10 functions such as ABS, TCS, AYC, etc., and the brake-by-wire supports ADAS technical requirements;
  • Electronically controlled parking brake system EPB: The electronic control system is integrated in the ESC controller and controls the EPB actuator through the ESC.
