Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] see figure 1 , an automatic anti-collision system for the front end of a heavy-duty truck, including an air reservoir 1, a brake foot valve 3, a brake chamber 5, an alarm, an electromagnetic pressure regulating valve 2, a four-way air joint 4, an air pressure sensor 6 and a central controller ECU; the four air ports of the four-way airway joint 4 can be exchanged for air connection. The central controller ECU is respectively connected with the brake pedal, the accelerator, the manual prohibition switch, the radar sensor installed on the front of the cab, the yaw sensor, and the vehicle speed sensor, so as to receive the brake pedal signal, the accelerator signal, the manual prohibition switch, etc. signal, radar sensor signal, yaw sensor signal and vehicle speed sensor signal. The alarm is electrically connected to the centra...

Abstract

The invention discloses an automatic collision avoidance system at the front end of a heavy duty truck. The automatic collision avoidance system comprises a gas storage cylinder (1), a solenoid regulator valve (2), a brake foot valve (3), a four-way gas channel connector (4), a brake gas chamber (5), a gas pressure sensor (6), an alarm and a central control unit ECU (Electronic Control Unit), wherein a gas inlet of the brake foot valve (3) is connected with a gas outlet of the gas storage cylinder (1); a gas inlet of the solenoid regulator valve (2) is connected with a gas outlet of the gas storage cylinder (1); a gas outlet of the brake foot valve (3), a gas outlet of the solenoid regulator valve (2), a gas inlet of the gas pressure sensor (6) and a gas inlet of the brake gas chamber (5) are correspondingly connected with four gas openings of the four-way gas channel connector (4); the gas pressure sensor (6) is electrically connected with the central control unit ECU; the central control unit ECU is electrically connected with the solenoid regulator valve (2). According to the automatic collision avoidance system, dangerous anticipation can be realized, automatic alarming and automatic braking measures can be taken, and automatic brake can be realized without depending on a driver so as to avoid accidents.

Description

technical field [0001] The invention relates to an active safety system of a heavy truck, more specifically to an automatic anti-collision system for the front end of a heavy truck, and belongs to the technical field of braking safety of a heavy truck. Background technique [0002] At present, the existing active safety systems of heavy trucks mainly include automatic alarm systems and automatic collision avoidance systems. Among them, the automatic alarm system can predict dangerous situations and send out sound or video alarms within the driver's reaction time to remind the driver to brake and slow down to avoid accidents; but this type of active safety system needs to rely on the driver's initiative Braking cannot actively avoid danger in the true sense. Among them, the automatic collision avoidance system can actively call the police and actively intervene in the vehicle braking system in the event of a pre-judged danger, and can automatically brake to avoid accidents w...
