Problems solved by technology
[0003] When the car is driving downhill, due to the influence of gravitational acceleration, etc., the speed of the car will become faster and faster, especially when driving on a downhill road curve, if the speed is too fast, the vehicle will easily drift, and in serious cases, it will even lose control, threatening Therefore, the driver needs to maintain control of the brake pedal and / or accelerator pedal at all times, which not only requires the driver to have rich driving experience, but also increases the burden on the driver, which is time-consuming and labor-intensive. , cumbersome operation

The embodiments of this application provide a vehicle turning control method and a control device. The vehicle turning control method comprises the following steps: determining whether a vehicle enters a turning state by detecting a deflection angle of steering wheel deflection when the vehicle travels along a downhill road, to determine that the vehicle needs to decelerate; and calculating a compensated fuel injection quantity based on a real-time fuel injection quantity corresponding to a detected real-time speed and a target fuel injection quantity corresponding to a preset first target speed, and braking the vehicle based on a braking force corresponding to the compensated fuel injection quantity, to assist control of stable running and safe running of the vehicle without frequent active operation of a driver. The method is simple and convenient, can reduce operating burden of the driver, assist the driver to control the driving speed of the vehicle, and is conducive to improving driving safety.
Description
technical field [0001] The present application relates to the technical field of vehicle safety driving, and in particular to a vehicle turning control method and control device. Background technique [0002] With the continuous development of science and technology, cars have gradually entered people's lives and become an indispensable travel tool for most families. , the safety and comfort in the process of car driving has also become a problem that people pay more attention to, especially the active safety of cars (assistant driving technology), which has become one of the research focuses of the automotive industry. [0003] When the car is driving downhill, due to the influence of gravitational acceleration, etc., the speed of the car will become faster and faster, especially when driving on a downhill road curve, if the speed is too fast, the vehicle will easily drift, and in serious cases, it will even lose control, threatening Therefore, the driver needs to maintain...
