Cruising function control method, system and device and readable storage medium

Abstract

The invention discloses a cruising function control method, system and device and a readable storage medium. The method comprises the steps of obtaining the actual automobile speed, the cruising target automobile speed and the steering angle of a steering wheel; according to the actual automobile speed and the cruising target automobile speed, calculating the corresponding initial cruising torque;judging whether or not the initial cruising torque exceeds the torque limiting section corresponding to the steering angle of the steering wheel; if yes, determining the boundary point closest to thecruising torque on the initial cruising torque limiting section as the final cruising torque; outputting the final cruising torque. The output cruising torque is regulated in the cruising period, andtherefore the automobile speed is kept within the safety traffic range all the time. If the turning speed is excessively high, the corresponding initial cruising torque exceeds the torque limiting section, the initial cruising torque is limited within the torque limiting section and then output, in other words, during turning, a driver rapidly brakes the automobile before braking measures are made, the phenomenon that risks are generated when the driver does not adopt braking measures in time is avoided, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobile drive control, in particular to a cruise function control method, system, device and readable storage medium. Background technique [0002] With the increasingly serious problems of global energy shortage and vehicle emission pollution, it has become a consensus to promote energy vehicles with low energy consumption and low emissions. In the power system scheme of new energy vehicles, pure electric and strong hybrid are the current mainstream directions. [0003] Cruise control is a method of car control, which can control the car in a driving state suitable for continuous and close to constant speed driving. The driver can use the cruise function during long-distance driving, so that there is no need to step on the accelerator for a long time, and avoid damage caused by long-term stepping on the accelerator. overworked. At present, the cruise function is basically popularized on conventional...

Problems solved by technology

In this driving situation, if the vehicle enters a certain curve, the driver cannot take braking measures in time. If the vehicle speed is high at this time and exceeds the maximum speed allowed by the curve, it may deviate from the lane, resulting in a car accident or even affecting the road. Personal safety
