CA 2426670
A remote start control system may include an engine speed data bus reader at the vehicle for reading the engine speed signal on the vehicle data communications bus, and a remote start controller at the vehicle and connected to a receiver and the engine speed data bus reader for operating the engine starter based upon a remote start transmitter and based upon the engine speed signal. In some embodiments, the engine speed signal may include a digital code, and the engine speed data bus reader reads the digital code and converts the digital code into a pulsed tachometer emulation signal for the remote start controller. In other embodiments, the engine speed data bus reader generates an output level based upon the digital code exceeding at least one threshold, such as an engine started or engine overspeed threshold. The remote start control system is readily interfaced to a vehicle having a data communications bus to thereby be able to operate using an engine speed signal.
