Embodiment Construction

[0015] The invention includes a power supply circuit, a digital radar probe 2, a vehicle body control module 1 and a LINBUS circuit. The digital radar probe 2 further includes a core probe, a center circumference, a receiving amplifier circuit, and a signal processing circuit. Among them, the power circuit provides power to other circuits; the probe core receives or emits ultrasonic waves; the middle week provides a boost circuit to provide energy for the probe core to emit ultrasonic waves; the receiving amplifier circuit receives the weak ultrasonic waves reflected from the back of the vehicle to amplify the recognizable electricity signal; the signal processing circuit performs filtering, detection and A / D conversion on the amplified electrical signal; the LINBUS circuit provides a transmission channel for the information. The probe core receives or emits ultrasonic waves;

Abstract

The invention discloses digital automobile backing radar. The digital automobile backing radar is characterized in that digital radar probes installed on the periphery of an automobile are connected with slave nodes of a Lin network respectively to be connected to an automobile body controller which is a main node and a gateway; and the automobile body controller is connected to an automobile instrument through the Lin network. By the adoption of the structure, the digital automobile backing radar is high in anti-interference capacity, better in EMC performance, more accurate and more stable in obstacle detection performance, easy to install and capable of adopting non-shielded wires, assisting a driver in overcoming the defects of view dead angles and blurred vision and improving driving safety.

Description

technical field [0001] The invention relates to the technical improvement of automobile driving equipment, in particular to a digital reversing radar. Background technique [0002] The full name of the reversing radar is "reversing anti-collision radar", also known as "parking assist device", which is a safety auxiliary device when the car is parked or reversed. It can inform the driver of the surrounding obstacles by sound or more intuitive display. It relieves the trouble caused by the driver's front, rear, left, and right visits when parking, reversing and starting the vehicle, and helps the driver eliminate the defects of blind spots and blurred vision, and improves driving safety. [0003] However, the existing reversing radar has poor anti-interference ability, is easily affected by external electromagnetic interference, and has a large error in the detection distance, which brings safety hazards to the driving of the vehicle. [0004] In view of the above problems, ...
