Embodiment Construction

[0065] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0066] See figure 1 , figure 1 It is a schematic flowchart of a control method for an unmanned vehicle provided by an embodiment of the present invention. In this embodiment, the control method of the unmanned vehicle is executed by the unmanned vehicle. Driverless cars can be electric driverless cars or new energy driverless cars. Such as figure 1 The control method of the shown driverless car may include the following steps:

[0067] S101: Obtain the current first driving speed value of the driverless car, and obtain the current second driving speed value of the vehicle or obstacle in front.

[0068] The driverless car can detect the current first driving speed value through the vehicle-mounted speed measuring dev...

Abstract

The present invention provides an autonomous vehicle, a control method for an autonomous vehicle and a control device thereof. The control method includes: obtaining the current first driving speed value of the autonomous vehicle, and obtaining the current first driving speed value of the vehicle or obstacle ahead. the second driving speed value; obtain the first distance value between the driverless car and the vehicle in front or the obstacle; according to the first distance value, the first driving speed value and the second The driving speed value is used to determine the expected driving speed value of the driverless car; according to the first driving speed value and the expected driving speed value, the torque control signal of the driver motor of the driverless car is determined; according to the The torque control signal controls the drive motor to adjust the first driving speed value. The control method of an unmanned vehicle of the present invention can safely stop the vehicle before colliding with a vehicle or obstacle that brakes suddenly in front, thereby preventing a rear-end collision with a vehicle or obstacle in front.

Description

technical field [0001] The present invention relates to the technical field of unmanned vehicles, in particular to an unmanned vehicle, a control method of the unmanned vehicle and a control device thereof. Background technique [0002] An unmanned vehicle is an intelligent vehicle that perceives the surrounding environment of the vehicle through the on-board sensor system, and automatically plans the driving route, controls the steering and speed of the vehicle, and controls the vehicle to reach the intended destination according to the road, vehicle position and obstacle information obtained through perception. car. [0003] However, in the prior art, the obstacle avoidance and deceleration control system of the unmanned vehicle is not very perfect, and the unmanned vehicle cannot safely stop under the conditions of substantial deceleration such as obstacle avoidance or parking. For example, when a vehicle with a higher speed enters the lane ahead, it will cause the smart...
