Abstract

The invention discloses a ramp starting control method for a vehicle. The ramp starting control method includes steps of S1, detecting rotation speeds and rotation directions of wheels of the vehicle; S2, computing acceleration of the vehicle according to the rotation speeds of the wheels when the wheels rotate anticlockwise; S3, computing sliding force of the vehicle according to the acceleration and the weight of the vehicle and controlling braking of the vehicle according to the sliding force; S4, reducing the braking pressure of the vehicle at a preset rate when increase of an opening of an accelerator of the vehicle is detected. The ramp starting control method for the vehicle has the advantages that braking force can be reduced according to change of the opening of the accelerator of the vehicle when the vehicle is started on a ramp, so that the vehicle can be started smoothly, the vehicle starting smoothness is improved, and the driving safety is guaranteed. The invention further discloses the vehicle and a ramp starting control device for the vehicle.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to a control method for a vehicle starting on a slope, a control device for a vehicle starting on a slope, and a vehicle with the control device. Background technique

[0002] Hill start is a situation that car drivers often encounter in daily driving. When driving a manual transmission vehicle, the driver mainly relies on the driver's recognition of the slope and driving skills to control the clutch pedal, brake pedal, and accelerator pedal to start on a slope. The automatic transmission car does not have a clutch pedal, only a brake pedal and an accelerator pedal. When a vehicle with automatic transmission starts on a slope, it mainly relies on the driver to control the speed and depth of releasing the brake pedal and stepping on the accelerator pedal. At present, automatic transmission vehicles mainly include AT, AMT, DCT, CVT, etc. Among them, AT and CVT are equipped with hyd...
