Abstract

The invention provides an electronic parking control method and system. The electronic parking control method comprises the following steps: 101, starting an electronic parking system; 102, judging whether a vehicle stays at a starting state or not; executing the step 103 when the vehicle stays at the starting state; executing the step 107 when the vehicle does not stay at the starting state; 103, judging whether the vehicle speed is greater than 0km / h; executing the step 104 when the vehicle speed is greater than 0km / h; executing the step 105 when the vehicle speed is less than or equal to 0km / h; 104, unlocking the electronic parking system; 105, judging whether the vehicle stays at a brake state or not; executing the step 104 when the vehicle stays at the brake state; executing the step 106 when the vehicle does not stay at the brake state; 106, judging whether the vehicle is located on a slope or stays at a low-speed running state; executing the step 104 when the vehicle is located on the slope or stays at the low-speed running state; 107, locking the electronic parking system. By adopting the electronic parking control method provided by the embodiment of the invention, the process that a shift lever is pushed into or unplugged from a gear P by a driver can be avoided, and the teeth fighting and damage problem of a parking gear can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and system for electronic parking. Background technique [0002] Automatic vehicles usually have a park gear. The parking gear of an automatic transmission vehicle is referred to as the P gear for short. The P gear is divided into two types: mechanical parking and electronic parking. At present, electronic parking is mostly used in high-end models. [0003] The electronic parking of the automatic transmission vehicle in the prior art is connected with the shift lever through the electric mechanism. When the shift lever is shifted out of the P gear, the electric mechanism controls the parking arm to be pulled out from the parking gear. The shift lever is shifted into the P gear, and the electric mechanism controls the parking arm to dial into the parking gear, which blocks the parking gear and locks the parking gear, thereby preventing the vehicle from movin...
