Embodiment Construction

[0022] Specific embodiments of the present invention are described in detail below:

[0023] like figure 1 As shown, the vehicle distance assistant control system for a heavy commercial vehicle of the present invention includes: a vehicle-mounted millimeter-wave radar 3 and a vehicle distance assistant controller 1 . The vehicle-mounted millimeter-wave radar 3 is installed in the front middle of the heavy-duty commercial vehicle, and the vehicle distance assistant controller 1 is installed in the cab of the heavy-duty commercial vehicle at a position convenient for the driver to observe and operate. The vehicle distance auxiliary control system cooperates with the electronically controlled engine 2 of the heavy-duty commercial vehicle, so that the vehicle can automatically maintain the vehicle distance or speed specified by the driver, thereby reducing driving fatigue. The electronically controlled engine 2 is an electronically controlled engine based on the CAN2.0 bus protoc...

Abstract

Disclosed are a heavy commercial vehicle distance control system and a control method of the heavy commercial vehicle distance control system. The system comprises a vehicle distance auxiliary controller, a vehicle-mounted millimeter-wave radar and an electronic-controlled engine, wherein the vehicle-mounted millimeter-wave radar and an electronic-controlled engine are used in a matched mode. The vehicle distance auxiliary controller comprises a controlling chip, two lines of independent CAN communication interfaces which are connected with the controlling chip, a human-computer interaction device and a system power source. By the adoption of the heavy commercial vehicle distance control system and the design of the two lines of independent CAN communication interfaces, radar data do not occupy a finished vehicle CAN bus resource, matching of a heavy vehicle and a vehicle-mounted millimeter-wave radar product is convenient, and the vehicles with CAN buses have good millimeter-wave radar generality.

Description

technical field [0001] The invention relates to a vehicle distance auxiliary control system, in particular to a vehicle speed and vehicle distance auxiliary control system of a heavy commercial vehicle and a control method thereof. Background technique [0002] The safe driving of vehicles is an important performance related to the life safety of drivers and the operation efficiency of traffic systems. Especially for heavy vehicles, the consequences of traffic accidents are more serious, and the loss of life and property is even greater. [0003] During the driving process of heavy-duty vehicles, keeping a certain distance from the vehicle in front is a common working condition. At this time, the driving conditions are simple, the duration is long, and the driver is prone to fatigue. Therefore, it is necessary to design a new type of distance assist control system for heavy commercial vehicles to reduce the driver's driving fatigue. [0004] In the prior art, although there...
