Embodiment Construction

[0012] As shown in the figure, the master brake cylinder 2 and the vehicle ECU 6 are equipped with a pressure sensor 1 on the master brake cylinder 2 (or the master brake pipeline), and the signal output terminal of the pressure sensor is connected to the vehicle ECU 6. The display status of the brake light is controlled according to the signal transmitted by the pressure sensor.

[0013] The vehicle ECU realizes the control of the display state of the brake light through the following structure: the brake light 3 is connected to the scintillator 8, the signal output terminal of the vehicle ECU is connected to the relay 7, and the relay controls the series circuit of the battery 5, the scintillator 8 and the brake light 3 on and off.

[0014] When an emergency occurs and the brake plate 4 is suddenly stepped on, the force applied to the pedal is greater than the usual braking force. According to Pascal's law, the force applied by the driver to the brake plate 4 will be multipl...

Abstract

The invention relates to a control device for an automobile brake lamp and a control method thereof. During the emergency braking of an automobile, the control device for the automobile brake lamp can make the brake lamp be in a display status under an emergency braking state. The technical proposal is as follows: the control device for the automobile brake lamp is provided with a main braking cylinder and an entire automobile ECU; and the control device is characterized in that a pressure sensor is arranged on the main braking cylinder; the signal output end of the pressure sensor is connected with the entire automobile ECU; and the entire automobile ECU controls the display status of the brake lamp according to the signal sent by the pressure sensor.

Description

technical field [0001] The invention relates to an automobile brake lamp control device and a control method thereof. Background technique [0002] Traditional automotive hydraulic braking is to amplify the force applied by the driver to the brake pedal and reflect it to the brake master cylinder. The brake master cylinder builds up the pressure of the entire brake pipeline to push each brake to achieve the braking of the whole vehicle. . During the whole process of braking, the brake light of the whole vehicle is in a state of lighting, so as to remind the cars behind to prevent rear-end collision accidents. There are certain flaws in the warning of the brake light, for example, when driving on the highway, the current vehicle brakes (the brake light sends out a warning). reduce) to judge whether the vehicle in front has adopted emergency braking; if the vehicle behind does not know that the vehicle in front has adopted emergency braking, improper handling will easily lea...
