Abstract

The invention provides an ESC system, an auxiliary downhill control method and a vehicle and relates to the technical field of vehicles. The ESC system comprises a speed obtaining unit used for obtaining the running speed of a vehicle when the vehicle runs downhill, a state obtaining unit used for obtaining the state of a braking pedal when the vehicle runs downhill, a speed recording unit used for recording the current running speed of the vehicle when it is detected that the braking pedal is changed to be in a released state from a stepped state and making the running speed serve as the target running speed, and a control unit used for controlling a speed changing box to lower the gear and adjusting the gear of the speed changing box to the gear matched with the target running speed. According to the ESC system, the auxiliary downhill control method and the vehicle, the dragging torque of an engine can be increased by controlling the speed changing box to lower the gear when the vehicle runs downhill, and therefore the deceleration generated by the dragging torque of the engine can be used for counteracting the acceleration generated when the vehicle runs downhill, the vehicle speed is maintained in a safe and stable range, and the uncomfortable feeling brought by vehicle speed fluctuation caused by braking interference is relieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an electronic stability control (ESC) system, a downhill assistance control method and a vehicle with the ESC system. Background technique [0002] In the current domestic automobile market, SUVs occupy a large market share. People in cities like to drive SUVs to the suburbs on weekends, away from the hustle and bustle of the city, and enjoy the fun of off-road adventures. When driving a vehicle on a field adventure, it is often easy to encounter a steep downhill road (such as an unpaved road with a slope greater than 30%). The steering wheel is a huge challenge for ordinary drivers (especially female drivers). It requires a perfect combination of courage and driving experience to control the vehicle, which raises a high level of driver's driving level. requirements, limiting the range of activities of ordinary drivers. [0003] In order to offset the downhill acceleration ge...
