Problems solved by technology

[0005] However, given the nature of wireless communications and the fact that the vehicle must listen to data from sensors it does not control (sensors equipped with other vehicles) there is a considerable risk that it will sometimes receive the wrong data

Embodiment Construction

[0033] Figure 1a An ego vehicle 10 and surrounding vehicles 12 are shown in which aspects of the invention may be implemented.

[0034] Ego vehicle 10 and surrounding vehicles 12 are motorized road vehicles. The ego vehicle 10 and the surrounding vehicles 12 are here trucks, but could alternatively be other heavy vehicles, or at least one of them could be a car.

[0035] The ego vehicle 10 includes on-board sensors 14 and a vehicle-to-vehicle (V2V) communication unit 16 . Onboard sensors 14 are adapted to provide sensor data about surrounding vehicles, such as surrounding vehicle 12 . On-board sensor 14 may be, for example, radar or a camera. On-board sensors 14 may be forward facing and adapted to provide sensor data about surrounding vehicles 12 ahead of host vehicle 10 . The sensor data about surrounding vehicles 12 may be, for example, the speed or acceleration or the position of surrounding vehicles 12 . Vehicle-to-vehicle communication unit 16 provides wireless commu...

Abstract

The invention relates to a method for diagnosing error of at least one of an ego vehicle (10) and a surrounding vehicle (12). The method comprises the steps: receiving (S1) sensor data about the surrounding vehicle (12) from an on-board sensor (14) of the ego vehicle (10) and vehicle to vehicle data from the surrounding vehicle (12) by the ego vehicle (10); comparing (S2) the received sensor dataand the received vehicle to vehicle data by the ego vehicle (10); and detecting (S3) a difference between the received sensor data and the received vehicle to vehicle data by the ego vehicle (10). Theego vehicle (10): stops (S4) receiving vehicle to vehicle data from the surrounding vehicle (12); registers (S5) a potential error of the ego vehicle (10); and reports (S6) a potential error of the surrounding vehicle (12) to at least one of the surrounding vehicle (12) and a remote server (18). The invention also concerns a method for diagnosing error of a surrounding vehicle (12).

Description

technical field [0001] The invention relates to a method for diagnosing errors in at least one of a host vehicle and surrounding vehicles. The invention also relates to a related method for diagnosing errors in surrounding vehicles. [0002] The invention is applicable to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described in relation to a truck, the invention is not limited to this particular vehicle but may also be used in other vehicles such as automobiles. Background technique [0003] Today's vehicles are equipped with on-board sensors, such as radars and cameras, to detect surrounding vehicles. This information is used to control the distance from the preceding vehicle in ACC (automatic / adaptive cruise control) driving, or to automatically brake the vehicle in the event of an imminent collision. Clearly, errors in the data can have serious consequences, and faulty sensors have caused crashes in some examples. ...
