Vehicle brake drive device

Abstract

The present invention relates to a vehicular brake driving device for receiving a speed-reducing control signal from a traveling control unit of an autonomous vehicle, receiving a status signal that follows the vehicle's operating status, and pressurizing the brake pedal or releasing the pressurization, thereby reducing the speed of the autonomous vehicle. According to the present invention, a control module rotates / drives a driving module with reference to a driving reference rotation angle of the driving module such that the degree of pressurizing the brake pedal can be accurately adjusted according to a speed-reducing control signal received from the traveling control unit, regardless of the installation height of the brake pedal of the vehicle and the angle and shape of a pressurizing surface, thereby enabling precise speed-reducing control of the autonomous vehicle; the contact point of a driving arm, which contacts the pressurizing surface of the brake pedal by means of rotation / driving of the driving module, is provided in the shape of a convex arc toward the brake pedal such that the driving arm slides along the pressurizing surface of the brake pedal and accordingly pressurizes the brake pedal or releases the pressurization; accordingly, the degree of increase / decrease of the speed-reducing force of the autonomous vehicle, resulting from rotation / driving of the driving module, can become constant, thereby improving the speed-reducing stability of the autonomous vehicle; and the control module sets the driving reference rotation angle of the driving module so as to correspond to the position in which the driving arm does not contact the brake pedal, thereby preventing unnecessary speed reduction that would otherwise occur as the driving arm, which has contacted the brake pedal, slightly pressurizes the brake pedal when no speed-reducing control is required.

Description

technical field [0001] The invention relates to a vehicle brake driving device. Background technique [0002] A vehicle is a means of transportation in which the driver assists the driver or passengers to reach the desired destination by driving on the ground by operating the steering wheel and the accelerator pedal and brake pedal as means of acceleration and deceleration. destination. [0003] This kind of vehicle has the advantage of being able to move the vehicle quickly over long distances, so it has become the first choice for a large population. However, for the driver of the vehicle, according to the distance to the destination and the traffic conditions in the driving section, there will be Spend more time driving the vehicle. [0004] Therefore, the research on the automatic driving device is continuously carried out, and the automatic driving device confirms the road conditions, adjacent vehicles and The location of things and road signals, etc., so as to perfo...

Problems solved by technology

[0006] However, there is a problem in the prior art that the brake is driven because the push rod presses the rod of the brake pedal due to the driving of the brake motor when the brake is driven, but the push rod for pressing the brake pedal is not provided Therefore, it is difficult to perform slight deceleration control based on the pressure of the brake pedal, and because the push rod slightly presses the brake pedal, unexpected vehicle deceleration may also occur during driving
