Abstract

The invention provides an electric car constant-speed cruising method. The method includes: detecting whether a user starts a cruising preparation action or not; if so, detecting whether the driving state and hardware state of an electric car satisfy a preset cruising condition or not; if so, starting cruising control and outputting cruising speed; during cruising, using the larger one of cruising torque and accelerator torque as the output torque and outputting the output torque so as to execute acceleration or deceleration when the situation that the user starts an acceleration mode or a deceleration mode is detected, and allowing the electric car to cruise at the current speed again when the situation that the user shuts down the acceleration mode or the deceleration mode and releases an accelerator is detected. By the method which is fast and easy to use, the constant-speed cruising response of the electric car is fast and rich in function. The invention further discloses an electric car constant-speed cruising device.

Description

technical field [0001] The invention relates to the technical field of vehicle information, in particular to a constant-speed cruise method and device for an electric vehicle. Background technique [0002] In recent years, the electric vehicle industry has developed rapidly, and the world's environmental protection requirements are getting higher and higher. The characteristics of zero pollution and zero emissions of electric vehicles have attracted much attention, and the prospects are promising. Taking my country as an example, electric vehicles have begun to enter the field of buses and taxis. Traditional mechanical cruise control systems can only be applied to traditional fuel vehicles, and there is no corresponding industry standard for electric vehicles. [0003] The traditional mechanical cruise control system needs to add additional hardware equipment to the system and other hardware support, which increases the cost and is cumbersome to operate.
