Embodiment Construction

[0051]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] Embodiments of the present invention provide a constant speed cruise control method, such as figure 1 As shown, the method includes:

[0053] Step 101: When the vehicle is in the state of constant speed cruise activation, detect the state of the accelerator pedal of the vehicle, and acquire the difference between the accelerator torque and the cruise torque of the vehicle.

[0054] Wherein, the state of the accelerator pedal includes a state of ...

Abstract

The invention provides a constant-speed cruise control method and device, a controller and a car. The constant-speed cruise control method comprises the steps that when the car is in a constant-speed cruise activated state, the state of an accelerator pedal of the car is detected, and the difference of the accelerator torque and the cruise torque of the car is obtained; and according to the state of the accelerator pedal and the difference of the accelerator torque and the cruise torque, the car is controlled to travel in the constant-speed cruise activated state according to the accelerator torque or the cruise torque. Therefore, through the scheme, according to whether the accelerator pedal is stepped down or not and the difference of the accelerator torque and the cruise torque, the car is controlled to start the surpassing mode or stopping the surpassing mode and does not exit from the constant-speed cruise activated state; and through judgment of dual conditions of the state of the accelerator pedal and the difference of the accelerator torque and the cruise torque, the redundancy rate of condition judgment is increased, and false triggering of the surpassing mode is avoided to the utmost extent.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a constant speed cruise control method, device, controller and automobile. Background technique [0002] During the constant speed cruise of the vehicle, the way the driver changes the current vehicle speed by stepping on the accelerator pedal is defined as the constant speed cruise override mode. The following are two representative technical solutions of the override mode. [0003] Solution 1: Chinese invention patent (CN201611082868) discloses a vehicle constant speed cruise control method, its definition: during the vehicle constant speed cruise process, if the driver changes the speed through the accelerator pedal, the constant speed cruise exits, and after the accelerator pedal is released Cruise control cannot be automatically restored. [0004] Scheme 2: Chinese invention patent (CN201210465140) discloses a constant speed cruising method and device for an elec...
