The invention discloses a method and device for controlling assisted turning of a vehicle, comprising: obtaining the current state information of the vehicle in real time; when the assisted turning function of the vehicle is in a standby state, judging whether the current state information of the vehicle satisfies the assisted turning activation condition; , the vehicle is controlled to enter the activation state of the auxiliary turning function, and according to the steering wheel angle, vehicle speed and brake pedal opening, the hydraulic control unit is controlled to apply pressure to the inner rear wheel cylinder when the vehicle is turning. The present invention judges the current state information of the vehicle acquired in real time, and controls the vehicle to enter the activation state of the auxiliary turning function when the activation condition of the auxiliary turning function is satisfied, and controls the hydraulic control unit to turn the inner rear wheel of the vehicle The cylinder exerts pressure, thereby reducing the turning radius of the vehicle, so as to realize the rapid turning and passing of the vehicle in a narrow space, improve the maneuverability of the vehicle, and help solve the problem of urban road traffic congestion.
Description
technical field [0001] Embodiments of the present invention relate to automobile braking technology, and in particular to a control method and device for assisting turning of a vehicle. Background technique [0002] In recent years, the number of cars has been increasing, and the urban road traffic is congested year by year. There are still many two-way two-lane lanes in the city with narrow lane widths. According to statistics, the minimum turning radius of various vehicles: 4.50m for miniature vehicles, 6.00m for small vehicles, 6.50-8.00m for light vehicles, 8.00-12.00m for medium-sized vehicles, 10.50-12.50m for articulated vehicles, 9.00m for ordinary fire engines, and 9.00m for large fire engines. 12.00m, 102.00m for ascending fire trucks, 16.00-20.00m for some special fire-fighting vehicles. The turning radius of urban road intersections is controlled according to the following standards (according to the red line of the road): main road: 20 meters to 30 meters, seco...
