Description

Technical Field

[0001] The utility model relates to the technical field of intelligent driving, and in particular to an intelligent driving controller supporting ETC. Background Art

[0002] At present, the advanced driver assistance functions equipped with intelligent driving controllers mainly include highway pilot driving assistance and city pilot driving assistance. When entering the highway from the city road or entering the city road from the highway, the two functions cannot automatically pass through the highway entrance and exit, and require the intervention of the driver, which limits the development of driving assistance functions. The main reason is that the highway toll collection system and the intelligent driving assistance system cannot work together. For the subsequent development of intelligent roads and intelligent driving, it is imperative to open up the vehicle-road interface.

[0003] The original intention of the Electronic Toll Collection (ETC) system is to save time on toll payment, improve traffic efficiency and save labor for service personnel at highway entrances and exits. However, the actual operation is not the case. There is still congestion at the ETC highway entrance. Sometimes the congestion at the ETC highway entrance is even higher than that at the manual highway entrance and exit, and even often leads to traffic accidents. The process of observing the congestion phenomenon is as follows:

[0004] 1. A vehicle carrying an on-board unit (OBU) device enters the ETC entrance and exit, and the ETC entrance and exit feedback that the tag is not detected, resulting in the vehicle being unable to pass;

[0005] 2. The driver of the vehicle re-inserts and removes the ETC chip card, and waits for the vehicle-mounted unit to communicate with the road section equipment (RSU) again. The vehicle can pass only when the communication is successful. If the communication is unsuccessful, if the highway staff intervenes, the highway staff will use the equipment to manually input the license plate number to help the vehicle-mounted unit and the roadside unit complete the communication. If there is no highway staff intervention, the vehicle needs to change to the manual entrance, but the ETC entrance and exit have isolation belts, and the vehicle needs to reverse to change the entrance and exit;

[0006] The main reason for the congestion is the poor reliability of the ETC system equipment, especially the on-board unit, which is a non-automotive-standard pre-installed mass-produced component with many quality problems. For example, the ETC chip card and the equipment are prone to poor contact, the OBC hardware chip circuit is damaged, the OUB software is stuck, etc. In addition, consumer-grade products do not have any fault alarms to the driver, and the driver has no way of knowing whether there is a fault in the OBU.

[0008] The technical solution adopted by the utility model to solve its technical problems is: an intelligent driving controller supporting ETC, comprising: a first control module, a SOC, a wireless transceiver unit and a CAN interface, the SOC comprising: an intelligent driving perception module, an intelligent driving environment module and an on-board ETC function module, the intelligent driving perception module is connected to the intelligent driving environment module, the intelligent driving environment module is connected to the on-board ETC function module, the on-board ETC function module is connected to the intelligent driving perception module, the on-board ETC function module is connected to the first control module, the wireless transceiver unit is connected to the on-board ETC function module, the wireless transceiver unit is connected to the ETC entrance and exit mechanism, the CAN interface is connected to the first control module, and the CAN interface is connected to the second control module.
