The invention relates to a redundant hardware and software architecture for autonomous vehicles. The redundant hardware and software architecture can be designed to enable vehicles to be operated in an autonomous mode while improving the reliability and/or safety of such vehicles. A system for redundant architecture can include a set of at least two redundant sensors coupled to a vehicle and configured to provide timestamped sensor data to each of a plurality of computing unit (CU) computers. The CU computers can process the sensor data simultaneously based on at least a time value indicative of an absolute time or a relative time and based on the timestamped sensor data. The CU computers provide to a vehicle control unit (VCU) computer at least two sets of outputs configured to instruct a plurality of devices in a vehicle and cause the vehicle to be driven.
本公开设计用于自动驾驶车辆的冗余硬件和软件架构。可以设计一种冗余硬件和软件架构以使得车辆能够以自动驾驶模式操作,同时提高这样的车辆的可靠性和/或安全性。一种用于冗余架构的系统可以包括一组至少两个冗余传感器,该组至少两个冗余传感器耦合到车辆,并且被配置为向多个计算单元(CU)计算机中的每个提供带时间戳的传感器数据。CU计算机可以至少基于指示绝对时间或相对时间的时间值并且基于带时间戳的传感器数据来同时处理传感器数据。CU计算机向车辆控制单元(VCU)计算机提供至少两组输出,该至少两组输出被配置为指示车辆中的多个设备并且引起车辆被驱动。
