The invention discloses a method and system of emergency parking of a vehicle on a slope. The method comprises the following steps that whether a person is in an operator seat or not is detected; if the person is in the operator seat, whether a vehicle slides forward or slides backward is judged according to an electrical level of a pre-marked driving direction identifier in the information sent by a wheel speed sensor; when the vehicle slides backward, an electronic parking handle is controlled to conduct parking braking automatically; when the vehicle slides forward, the electronic parking handle is controlled to conduct parking braking automatically, and a front brake is controlled to conduct braking through a braking anti-lock braking system electromagnetic valve. According to the method and system of emergency parking of the vehicle on the slope, a more suitable parking braking method is selected according to a vehicle sliding direction, so that the problem that a method of parking of the vehicle on the slope in the prior art cannot meet practical demands can be solved.
Description
technical field [0001] The invention relates to the technical field of electronic control, in particular to a method and system for vehicle emergency parking on slopes. Background technique [0002] With the increasing number of vehicles, the active safety of vehicles has been paid more and more attention. In life, we often encounter the phenomenon that the vehicle "slips down" because the parking handle is not pulled after parking, causing serious consequences of loss of life and property. [0003] The vehicle emergency slope parking method in the prior art mainly detects whether there is anyone on the main seat through the seat pressure sensor, and detects whether the current gear is forward gear or reverse gear through the gear sensor. If there is no one on the main seat, and If the current gear is a forward gear or a reverse gear, the braking system is controlled to brake. However, the current gear does not directly reflect whether the current vehicle rolls: even if th...
