Abstract
A vehicle control system comprises an industry standard CAN network with a number of nodes distributed around the vehicle for controlling corresponding parts of the vehicle. One such node is located in the housing of the vehicle interior rearview mirror and directly controls the reflectivity of an electro-optic mirror unit, in accordance with the state of at least one ambient light sensor and a remote keyless entry device. The node also communicates via an ISO9141 interface with a number of slave controllers such as a sun-roof control module mounted adjacent a sun-roof and a roof control module mounted in a roof housing. By this means the UCM exercises indirect control of the sun-roof in accordance with the state of a switch, and exercises indirect control of various lamps GEN1, GEN2, FLL and FRL in the roof housing in accordance with the state of switches Gen, FL and FR mounted in the roof housing or, in the case of the lamps GEN1 and GEN2, when a vehicle door is opened.
