Anti-tailgating system and method

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.

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.
