Abstract
A turn signal modulation system is provided for controlling turn signals of a host vehicle. The turn signal modulation can include a vehicle braking sensor; a vehicle attitude sensor and a turn signal modulation circuit. The turn signal modulation circuit can include a communication receiver, communicatively coupled to receive information from the vehicle braking sensor and the vehicle attitude sensor; and a decision circuit with an input communicatively coupled to receive sensor information from the communication receiver. The sensor information can include information indicating an amount of braking force applied to the host vehicle and information indicating changes in vehicle attitude. The decision circuit may determine whether to actuate the turn signals using the amount of braking force applied to the host vehicle and the change in vehicle attitude.
