Vehicle and uphill control method and device thereof

Abstract

The invention discloses a vehicle uphill control method. The vehicle uphill control method comprises the steps of detecting a vehicle accelerator depth when a vehicle is in an uphill state; detecting gear signals of the vehicle, wheel output rotating speed signals and brake pedal signals when the accelerator depth is smaller than or equal to a first threshold; and when the vehicle is at a forward gear or a neutral position, the wheel output rotating speed is negative and the brake pedal signals are not detected, utilizing an automatic transmission controller of the vehicle to control an electronic parking system of the vehicle to lock parking ratchet wheels of the vehicle so as to enable the vehicle to be in a parking state. By the control method, excessive wear of a brake block of the vehicle can be avoided, manipulation pressure of a driver is relieved, driving safety is improved, and fuel oil use is effectively reduced. The invention further discloses a vehicle uphill control device and the vehicle with the upslope control device.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method for controlling a slope uphill of a vehicle, a device for controlling a slope uphill of a vehicle, and a vehicle with the device for controlling a slope uphill. Background technique [0002] At present, most automobiles do not have an automatic parking system or an uphill assist system, and it is easy for the car to slip behind when temporarily stopping during uphill driving or starting on an uphill road. Among them, in order to prevent the car from slipping back, cars with automatic transmission often use the combination of forward gear and hand brake or foot brake to prevent the car from slipping back, while cars with manual transmission sometimes need brakes, clutches and accelerators to prevent the car from slipping back. A phenomenon that is controlled together, which brings a lot of difficulty to the operation. Although some cars currently integrate uphil...

AI Technical Summary

Problems solved by technology

[0003] Therefore, at present, the cars that do not adopt the automatic parking system or the uphill assist system are difficult to operate, and the phenomenon of the car slipping behind when starting uphill is easy to occur, resulting in accidents.

However, the uphill assist system that controls the brake pads makes the brake pads that are frequently used when going downhill when driving on mountain roads work frequently when going uphill, which directly leads to double wear of the brake pads, and even malfunctions when driving on mountain roads. foreseeable dangerous consequences

In addition, the cars that use the uphill assist system that controls the brake pads are all used in high-end cars, and the required auxiliary electronic braking system is expensive, complex in structure, and difficult to maintain after sales.
