Active safety systems of vehicles with graphical microprocessors

摘要

A system of a vehicle includes an engine control module (ECM), a first processor module, sensors, a second processor module, and a third processor module. The ECM controls engine actuators based on driver inputs to a steering wheel, an accelerator pedal, a brake pedal, and a cruise control system. The first processor module includes a first microprocessor and selectively actuates at least one of an electric power steering motor, friction brakes, and a throttle valve based on processed data. The sensors sense features outside of the vehicle. The second processor module includes a second microprocessor and generates the processed data based on data from the sensors. The second microprocessor is a graphical microprocessor. The third processor module includes a third microprocessor and generates an indicator of whether a fault is present in the second processor module.

1. A system of a vehicle, comprising:
an engine control module (ECM) that controls engine actuators based on driver inputs to a steering wheel, an accelerator pedal, a brake pedal, and a cruise control system; a first processor module that includes a first microprocessor and that selectively actuates at least one of an electric power steering motor, friction brakes, and a throttle valve based on processed data; sensors that sense features outside of the vehicle; a second processor module that includes a second microprocessor and that generates the processed data based on data from the sensors, wherein the second microprocessor is a graphical microprocessor; a third processor module that includes a third microprocessor and that generates an indicator of whether a fault is present in the second processor module; and an external object calculation module that includes:
a fourth processor module that includes a fourth microprocessor and that, only in response to an indication that the fault is present in the second processor module, selectively actuates at least one of the electric power steering motor, the friction brakes, and the throttle valve based on second processed data;a fifth processor module that includes a fifth microprocessor and that generates the second processed data based on the data from the sensors,wherein the fifth microprocessor is a graphical microprocessor; anda sixth processor module that includes a sixth microprocessor and that generates an indicator of whether a fault is present in the fifth processor module.
