Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] During the running of the car, the object that makes the car brake is the driver's foot, and the sensor (3) is used to sense the position of the driver's right foot. If the driver is ready to brake, the sensor (3) detects the signal, and the sensor will The signal is passed to the control unit (2). Specifically, the sensor is a capacitive proximity switch, which detects whether the distance between the pedal and the driver's foot is within a preset range, and outputs a sensing signal if this signal is detected.

[0020] The control unit (2) and the sensor (3) are connected to each other, and are used to receive the signal of the sensor on the accelerator or the brake pedal, the gear position signal and the cruise constant speed signal.

[0021] The brake lamp (4) is connected to the control unit (2) through a lamp driving circuit, and is used for receiving a con...

Abstract

The invention provides a car intelligent brake early warning method and device. The device comprises a sensor, a controller unit and a stop lamp; the sensor is arranged on a brake pedal and an accelerator pedal of a car and is used for sensing the position of the right foot of a driver; the controller unit is connected with the sensor and is used for receiving a detection signal from the sensor, processing the signal and outputting a control signal; the stop lamp is used for receiving a control signal sent from a controller and sending early warning information of a light signal with fast and slow flashing to prompt a car to prepare for braking. The device is simple in structural principle, high in practicability, convenient to mount, obvious in early warning prompt effect before braking, low in manufacturing cost, good in use stability and convenient to popularize, effectively solves the difficult problem that the early warning information cannot be output before braking, and belongs to a new direction of car initiative safety in the future.

Description

Technical field: [0001] The invention relates to the field of automobiles, in particular to an automobile brake early warning method and device. Background technique: [0002] Along with the development of automobile and traffic industry, automobile because of rear-end collision and collision accident takes place larger proportion in all traffic accidents. If the driver can be reminded before the accident and certain safety measures are taken, it will be very useful to reduce the occurrence of automobile rear-end collision accidents, and at the same time, it can make the traffic system smoother and reduce energy consumption. Existing braking system is that when the driver steps on the brake pedal, the brake light sends a red light signal. The driver of the vehicle behind detects this light signal and takes corresponding measures. But when the car driver was ready to brake, there was no signal to warn the rear vehicle driver, and the rear vehicle driver would cause a rear-e...
