Embodiment Construction

[0023] The present disclosure will be described more fully with reference to the accompanying drawings that illustrate preferred embodiments. The drawings are provided to provide a general understanding of the structure of various embodiments. However, the present disclosure may be embodied in many different forms. These drawings should not be construed as limiting.

[0024] figure 1 A multi-vehicle system 10 is shown with a host vehicle 12 receiving data via a wireless channel 11 via a master V2V module 14 which in turn may be used to alert the driver of the host vehicle of nearby or potential road hazards. The system 10 utilizes a remote vehicle 16 in an area that transmits data (eg, data based on SAE J2735) through a remote V2V module 18 . The V2V modules 14, 18 preferably include dedicated short-range communication (DSRC) antennas 14a, 18a, respectively, for transmitting data and creating an ad hoc network for communication with nearby vehicles. Each vehicle also prefe...

Abstract

A system and method are provided for identifying a potential road hazard in a host vehicle based on a remote vehicle. The host vehicle has a host vehicle-to-vehicle (V2V) module and a host advanced driver assistant system (ADAS) module, such as a system employing the ADASIS standard. The remote vehicle also has a remote V2V module that provides position data, and one or more of, longitudinal acceleration data, steering angle change rate data, braking system data, anti-lock braking status and stability control system status of the remote vehicle. The host vehicle receives the position data of the remote vehicle using the host V2V module and determines if the remote vehicle is in the main path zone (MPZ) of the host vehicle. The system determines a potential road hazard when it receives a signal indicating any of the following are true, the longitudinal acceleration data and / or the steering angle change rate data of the remote vehicle exceeds a predetermined threshold, the anti-lock braking system of the remote vehicle is activated, or the stability control system of the remote vehicle is activated. The system indicates the potential road hazard to a driver of the host vehicle when a potential road hazard is identified and the remote vehicle is in the MPZ of the host vehicle.

Description

technical field [0001] The present invention relates to alerting drivers of potential road hazards ahead of a vehicle's path, and more particularly, to utilizing vehicle-to-vehicle (V2V) networks to identify road hazards. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Efforts have been underway for some time to establish standards for technologies that allow drivers within a defined geographic area to "talk" to each other by participating in ad hoc vehicle-to-vehicle (V2V) networks where data is shared between participating vehicles and develop this technology. Various suitable V2V systems and protocols are disclosed in US Patent Nos. 6,925,378, 6,985,089, and 7,418,346, each of which is hereby incorporated by reference in its entirety. [0004] According to one proposal, data is shared between vehicles using a Dedicated Short Range Communication...
