Safe Mode

The safe mode is entered in case of system problems such as:

• Incoherent inputs on monitored signals. In this case, safe mode is the debouncing time before the inputs are considered INVALID. Note that today, we have no way to detect if the rain/light sensor is in working operation or not. It means that a driver action will be required in case of failure of this sensor;
• Loss of the CAN frame containing the monitored signal:
• Loss of the CAN network: CAN goes to BUS OFF state, safe mode is the time necessary for detecting the BUS OFF state.

In all cases, the action in safe mode is to maintain the previous state of the system (for lighting and wiping). The list of monitored signals is the same as in rescue mode
