Abstract :
In order to reduce the vehicle rear collisions and the damage degrees on passengers, we adopt the dot matrix display technology and the vehicle high positioned brake reminder technology based on CAN bus. The designed high positioned brake reminder system is composed by the nodes based on CAN bus. The first node is the sensor data acquisition node based on SCM. The brake position sensor in the node converts the acquired position signals into electric signals, and transmits them to the SCM for data processing through AD conversion. The display unit is the second node of the system. The CAN bus control part is mainly composed by two core chips, SJA1000 and PCA82C250. It can not only display the reminder information when braking, but remind rear driver aiming at different situations such as displaying brake abruptness, avoiding or reduce the vehicle rear collisions. The manufacturing cost of the system is cheap.
