Vehicle control method and device

Abstract

The invention discloses a vehicle control method and device. The vehicle control method comprises the following steps of detecting the motion speed and the motion direction of a first obstacle aroundan unmanned vehicle; determining whether a preset triggering condition is satisfied based on the movement speed and the movement direction of the first obstacle; calculating a plurality of motion parameters of the unmanned vehicle and the first obstacle in each of a plurality of available control modes of the unmanned vehicle in the traveling process when the preset triggering condition is determined to be satisfied, and detecting the first motion tracks of other obstacles except the first obstacle; determining a control mode in which the unmanned vehicle impacts only the first obstacle basedon a plurality of motion parameters and first motion tracks of other obstacles; calculating the collision loss value when the unmanned vehicle collides with the first obstacle under each control mode;and selecting a second motion track corresponding to the minimum collision loss value as a target track, and controlling the unmanned vehicle to run based on the target track.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle control method and device. Background technique [0002] In related technologies, when controlling unmanned vehicles, the general concern is how to find the shortest path for the unmanned vehicle and control the driving of the unmanned vehicle according to the shortest path; but this way of controlling the unmanned vehicle, Due to different control systems during driving, it is difficult to deal with vehicle collisions accordingly. If an unmanned vehicle collides with other vehicles or with other obstacles, it will cause high economic losses. It does not consider the situation when the unmanned vehicle collides, which reduces the user's interest in using it. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a vehicle control method and device t...

If an unmanned vehicle collides with other vehicles or with other obstacles, it will cause high economic losses. Does not take into account the situation when a driverless vehicle collides, reducing user interest
