Embodiment 1

[0025] Such as figure 1 As shown, a vehicle-mounted device for danger perception and prevention and control includes: a distance sensor, a vehicle-mounted MCU, a speed sensor, an acceleration sensor, a timing module, an alarm module, a TFT display screen, an ECU control unit, and an infrared detector.

[0026] The distance sensor includes an ultrasonic emitting unit and two ultrasonic receiving units, and the two ultrasonic receiving units are respectively arranged on both sides of the ultrasonic emitting unit at the middle position. The vehicle-mounted MCU is an I.MX6 4-core processor based on the ARM architecture, specifically a 4-core processor of the I.MX6 ARM CordecA9. The speed sensor is a linear speed sensor. The acceleration sensor is a piezoelectric acceleration sensor. The timing module includes at least one clock circuit, and the precision of the timing module is 1 ms. The alarm module issues an alarm by means of sound and / or flickering and / or vibration. The ECU...

Embodiment 2

[0029] A method for risk perception and prevention and control, implemented by a vehicle-mounted device for risk perception and prevention and control in Embodiment 1, the specific steps are as follows:

[0030] The ultrasonic transmitting unit of the distance sensor emits ultrasonic waves, and the ultrasonic waves are emitted to the front of the vehicle in a fan-shaped plane. The two ultrasonic receiving units of the distance sensor receive the reflected ultrasonic waves, and at the same time transmit and receive data to the vehicle-mounted MCU. The vehicle-mounted MCU obtains the position data of the vehicle in front relative to the vehicle through calculation. After more than three groups of data collection, the vehicle-mounted MCU calculates the speed and acceleration of the vehicle in front in combination with the timing data of the timing module, and compares the speed and acceleration values ​​of the vehicle measured by the speed sensor and the acceleration sensor to cal...

Abstract

The invention discloses a vehicle-mounted device for danger perception, prevention and control. The device comprises a distance sensor, a vehicle-mounted MCU (microprogrammed control unit), a speed sensor, an acceleration sensor, a timing module, an alarm module, a TFT (thin film transistor) display screen, an ECU (electronic control unit)) and an infrared detector. The vehicle-mounted device for danger perception, prevention and control is convenient to mount, easy to arrange and powerful in function, has the danger perception function for sudden approaching of front vehicles and people during vehicle driving, can directly perform emergency state control on a vehicle, greatly reduces the occurrence probability of traffic accidents and has broad application prospect in the field of driving safety of the vehicle.

Description

technical field [0001] The invention relates to a vehicle driving safety device, in particular to a vehicle-mounted device for risk perception and prevention and control. Background technique [0002] Due to the small range of vision in the driver's cab, there is often a blind spot, which generally does not affect normal driving. If you can’t see or see clearly, wait until the driver is very close to the pedestrian in front of you before reacting, it may be too late to brake the vehicle, resulting in traffic accidents, especially when the driver is not concentrated enough or reacts quickly enough, it is easy to cause such accidents. [0003] The most common situation is that the vehicle in front brakes suddenly, and the rear vehicle that is running normally will often cause a rear-end collision because it is too late to brake. If there is a vehicle that warns the vehicle that is quickly approaching itself or the person who is rapidly shortening the distance from itself, th...
