Abstract

The embodiment of the invention discloses a steering road feeling simulation method and device, a steer-by-wire system and a vehicle. The method comprises the following steps: acquiring vehicle state data; determining a road surface load moment according to the vehicle state data; determining a virtual assistance torque according to the vehicle state data; obstacle encountering torque is determined according to the vehicle state data; determining parking torque according to the vehicle state data; determining dead point protection torque according to the vehicle state data; and calculating a road feeling simulation target torque, wherein the road feeling simulation target torque = the road surface load torque-the virtual assistance torque-the obstacle encountering torque-the parking torque-the dead point protection torque. Wherein the vehicle state data comprises a torque request state, a steering wheel angle, a steering wheel rotating speed, a steering wheel torque, a vehicle speed, a wheel speed and the like. According to the embodiment of the invention, the simulated road feeling is transmitted to the hand of the driver, the driving hand feeling of the driver is improved, and more road surface information is provided for the driver. The road feeling of the driver is improved, and the driving experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to vehicle steering technology, and in particular to a steering feel simulation method and device, a steer-by-wire system and a vehicle. Background technique [0002] With the development of technology, the steer-by-wire system of vehicles is also constantly improving. [0003] The existing steer-by-wire system cannot transmit enough road surface information through the steering wheel, so the driver cannot obtain a good feel and sufficient road feeling. [0004] How to ensure the driving feel and road feeling, and improve the driving experience and other operational feelings are the key research topics in the field of steer-by-wire. Contents of the invention [0005] The invention provides a steering road feel simulation method, which is used to improve the driver's driving feel, provide the driver with more road surface information, and improve the driver's road feel. thereby improving the driving experi...
