Electronic accessory system for a vehicle

摘要

An electronic accessory system for a vehicle includes an accessory module housing electronics, which includes a CMOS camera and a vehicle bus node and a digital signal processor. When the accessory module is mounted at a vehicle windshield, the vehicle bus node is connected to a vehicle bus of the vehicle. At least one of (a) data generated by the electronics is conveyed to the vehicle bus via the vehicle bus node and (b) the vehicle bus conveys data to the electronics via the vehicle bus node. The digital signal processor is operable at a computational speed of at least 75 million instructions per second, and may include at least one of (a) at least 40 kilobytes of on-chip memory, (b) at least one serial port, (c) at least one DMA port, (d) at least one timer and (e) at least one interrupt capability.
