Abstract

The invention discloses a control method, device and system for preventing a vehicle from ramp sliding and belongs to control methods for preventing vehicles from ramp sliding. The method includes the steps that when the situation that the vehicle is located on a ramp is detected out, the operation intention of a vehicle driver is analyzed; if the operation intention of the driver is parking intention, a parking system is controlled to perform parking braking; if the operation intention of the driver is starting intention, whether power of a drive system of the vehicle is already established and meets the preset condition of starting without ramp sliding or not is judged; and if the preset condition of starting without ramp sliding is met, the parking system is controlled to cancel parking braking. By means of the control method, device and system for preventing the vehicle from ramp sliding, ramp starting without ramp sliding can be achieved intelligently by delaying cancellation of parking braking, and smoothness of ramp starting can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, device and system for vehicle slope prevention. Background technique [0002] The car of the manual air pressure braking system used on the automobile of the prior art usually has the phenomenon of sliding when starting on a slope. The sliding slope is due to the fact that the clutch is disconnected and fully combined resulting from power interruptions. If the car slides downhill, it will cause the engine to stall, shake when starting, and the ride comfort will be poor, and if it is serious, it will cause traffic accidents such as collision with the rear car. Some experienced drivers usually use the clutch semi-linkage control method to avoid the vehicle's slippery slope, but this method has high requirements for the driver's operation, and the driver needs to judge the different slopes and vehicle loads. Also can't avoid car slippery slope completely. In...
