Anti-tailgating system and method
First Claim
1. An anti-tailgating vehicle system, comprising:
- a communication bus on a host vehicle;
a forward vehicle sensor sensing a forward vehicle in front of the host vehicle, the forward vehicle sensor transmitting a forward vehicle message to the communication bus based on a distance to the forward vehicle;
an electronic control unit receiving the forward vehicle message from the communication bus and determining a relative speed between the host and forward vehicles based on the forward vehicle message, if the forward vehicle message indicates the host vehicle is not within a safe zone range relative to the forward vehicle while the host vehicle cruise control system is not engaged and while the relative speed is less than a predetermined threshold, the electronic control unit transmitting a host vehicle control message to the communication bus for limiting a torque of the host vehicle.

Abstract
An anti-tailgating vehicle system includes a communication bus on a host vehicle, a forward vehicle sensor that senses a forward vehicle in front of the host vehicle, and an electronic control unit. The forward vehicle sensor transmits a forward vehicle message to the communication bus based on a distance to the forward vehicle. The electronic control unit receives the forward vehicle message from the communication bus and determines a relative speed between the host and forward vehicles based on the forward vehicle message. If the forward vehicle message indicates the host vehicle is not within a safe zone range relative to the forward vehicle while a host vehicle cruise control system is not engaged, the electronic control unit transmits a host vehicle control message to the communication bus for limiting a torque of the host vehicle.

12. A method for reducing tailgating of a host vehicle, the method comprising:
-
sensing a forward vehicle in front of the host vehicle by a forward vehicle sensor; determining a distance to the forward vehicle based on a forward vehicle message transmitted from the forward vehicle sensor; determining a relative speed between the host and forward vehicles based on the forward vehicle message; and if the host vehicle is not within a safe zone range relative to the forward vehicle while the host vehicle cruise control system is not engaged and while the relative speed is less than a predetermined threshold, limiting a torque of the host vehicle. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for reducing tailgating of a host vehicle, the method comprising:
-
sensing a forward vehicle in front of the host vehicle; transmitting a forward vehicle message to a host vehicle communication bus based on a distance from the host vehicle to the forward vehicle; receiving the forward vehicle message by an electronic control unit from the communication bus; determining a relative speed between the host and forward vehicles based on the forward vehicle message; and if the forward vehicle message indicates the host vehicle is not within a safe zone range relative to the forward vehicle while the host vehicle cruise control system is not engaged and while the relative speed is less than a predetermined threshold, transmitting at least one of a plurality of a host vehicle control messages to the host vehicle communication bus for limiting a torque of the host vehicle. - View Dependent Claims (19)
