Problems solved by technology

At present, tracked vehicles are developing towards high speed, high power and high maneuverability. The increase in vehicle speed and effective load requires higher and higher braking performance of the vehicle. The traditional single mechanical brake cannot meet this demand. The side-independent electric drive crawler vehicle not only has wire-controlled hydraulic brakes, but also has an electric drive method in which the driving motor drives the driving wheel through the side transmission, and can also use the driving motor for electric braking. The advantage of motor braking is that it has strong high-speed braking ability , the braking response is fast, and it has the function of energy recovery; the disadvantage is that the braking torque of the motor is determined by its own characteristics, especially the working conditions of the double-sided independent electric drive tracked vehicle are complicated, and there are many modes. The hydraulic braking system and the motor braking system The combined braking is of great significance

Embodiment Construction

[0019] like figure 1 As shown, the present invention includes a multi-mode braking control method for a double-sided independent electric drive crawler vehicle, including the following steps, including the following steps:

[0020] Judging whether the operator controls the vehicle during the driving process, if not, enter the autonomous coasting braking mode; if so, enter the normal driving judgment;

[0021] Normal driving judgment, if yes, enter the service braking mode; if not, enter emergency emergency braking judgment;

[0022] Emergency braking judgment in emergency situation, if yes, enter emergency braking mode; if no, return to normal driving judgment.

[0023] In the autonomous coasting braking mode, the driver of the tracked vehicle does not operate, and the vehicle coasts autonomously until the vehicle speed reaches 0, completing the autonomous parking. The control method is as follows: When the vehicle is running, the operator releases the accelerator pedal and ...

Abstract

The invention relates to the technical field of tracked vehicle braking, in particular to a multi-mode braking control method for a bilateral independent electrically-driven tracked vehicle, which adopts combined control of a drive-by-wire hydraulic braking system and a motor braking system, and performs braking control in different modes when the form state of the vehicle is judged. The braking mode comprises an autonomous sliding mode, an emergency braking mode, a traveling braking mode and a parking braking mode. After the method is adopted, different combined braking control methods are provided according to different braking working conditions on the basis of the bilateral independent electrically-driven crawler, the vehicle is controlled by adjusting the driving motor braking system and the hydraulic braking system, and it is ensured that the vehicle is safe and stable in different braking modes.

Description

technical field [0001] The invention relates to the technical field of crawler vehicle braking, in particular to a multi-mode braking control method for a double-sided independent electric drive crawler vehicle. Background technique [0002] The braking performance of a tracked vehicle refers to the performance of the vehicle to decelerate or stop during the driving process. Good braking performance is an important guarantee for the safety and reliability of the tracked vehicle. At present, tracked vehicles are developing in the direction of high speed, high power and high maneuverability. The increase of vehicle speed and the increase of effective load have higher and higher requirements on the braking performance of the vehicle. The traditional single mechanical brake cannot meet this demand. The side independent electric drive crawler not only has wire-controlled hydraulic braking, but also has an electric drive method in which the drive motor drives the driving wheel thr...
