Abstract
A vehicle control method, vehicle and non-transitory computer readable storage medium that enables a current transmission ratio of a vehicle to be decreased prior to a driver turning a steering wheel so that a larger steering angle of a wheel can be obtained when the driver turns the steering wheel at a smaller angle in emergency driving situations.
Claims16
A vehicle control method, comprising:
- monitoring an accelerated speed of a target object in front of a vehicle, wherein a moving direction of the target object is in a same direction as the moving direction of the vehicle;
- detecting an obstacle in front of the vehicle, wherein the obstacle is a static obstacle, or a dynamic obstacle that is moving in a different direction than the moving direction of the vehicle;
- reducing a transmission ratio of the vehicle to a target transmission ratio under a condition that the accelerated speed of the target object in front of the vehicle meets a preset condition and the obstacle is detected in front of the vehicle;
- and
- maintaining the transmission ratio of the vehicle in response to determining that the accelerated speed of the target object meets the preset condition under the condition that a steering angle of a steering wheel of the vehicle is greater than or equal to a first preset angle,
- wherein the transmission ratio is a ratio of the steering angle of the steering wheel of the vehicle to a steering angle of a wheel of the vehicle.

A vehicle, comprising:
- a processor;
- and
- a memory, configured to store instructions executable by the processor, wherein
- the processor is configured to:
- monitor an accelerated speed of a target object in front of the vehicle, wherein a moving direction of the target object is a same direction as the moving direction of the vehicle;
- detect an obstacle in front of the vehicle, wherein the obstacle is a static obstacle, or a dynamic obstacle that is moving in a different direction than the moving direction of the vehicle;
- reduce a transmission ratio of the vehicle to a target transmission ratio under a condition that the accelerated speed of the target object in front of the vehicle meets a preset condition and the obstacle is detected in front of the vehicle;
- and
- maintain the transmission ratio of the vehicle in response to determining that the accelerated speed of the target object meets the preset condition under the condition that a steering angle of a steering wheel of the vehicle is greater than or equal to a first preset angle,
- wherein the transmission ratio is a ratio of the steering angle of the steering wheel of the vehicle to a steering angle of a wheel of the vehicle.

A non-transitory computer-readable storage medium, storing instructions for controlling steering of a vehicle, the instructions when executed by a processor cause the processor to perform a method comprising:
- monitoring an accelerated speed of a target object in front of the vehicle, wherein a moving direction of the target object is a same direction as the moving direction of the vehicle;
- detecting an obstacle in front of the vehicle, wherein the obstacle is a static obstacle, or a dynamic obstacle that is moving in a different direction than the moving direction of the vehicle;
- reducing a transmission ratio of the vehicle to a target transmission ratio under a condition that the accelerated speed of the target object in front of the vehicle meets a preset condition and the obstacle is detected in front of the vehicle;
- and
- maintaining the transmission ratio of the vehicle in response to determining that the accelerated speed of the target object meets the preset condition under the condition that a steering angle of a steering wheel of the vehicle is greater than or equal to a first preset angle, wherein the transmission ratio is a ratio of the steering angle of the steering wheel of the vehicle to a steering angle of a wheel of the vehicle.
