Abstract

The embodiment of the invention discloses a unilateral parking control method and device. The method comprises the steps that an IBS brake boosting system and an ESP vehicle body stabilizing system determine vehicle speed signals according to N wheel speed sensor signals sent by N wheel speed sensors respectively; under the condition that the vehicle speed signals meet a preset vehicle speed range, the IBS and the ESP respectively judge whether a parking triggering condition is met or not; and if the parking triggering condition is met, the IBS and the ESP control a first braking device and asecond braking device of the vehicle to park the vehicle correspondingly, and the first braking device and the second braking device are independent of each other. According to the invention, the parking safety can be improved, and the manufacturing cost of the vehicle is reduced.

Description

technical field [0001] The invention relates to the field of parking systems for new energy vehicles, in particular to a method and device for controlling unilateral parking. Background technique [0002] The national standard GB21670 stipulates that for a passenger car equipped with an EPB electronic parking control system, when the wiring harness or controller other than the power line fails, the vehicle can still park with a full load on a slope with a slope of 8%. For this reason, for vehicles equipped with a parking gear (P gear) locking mechanism, when the vehicle is in P gear, the internal locking mechanism locks the gearbox. [0003] Considering the cost, energy saving, and structure of the vehicle, the new energy vehicle cancels the parking gear (P gear). Therefore, in the case of the failure of the EPB electronic parking control system, it cannot meet the above parking requirements on slopes, resulting in Safety issues when the vehicle is parked follow.
