A vehicle safety electronic control system () including a first microcontroller (), a second microcontroller (), and an inter-processor communication path () for bi-directional transfer of data between the microcontrollers (). The system has a first mode of inter-processor communication in which the first microcontroller () acts as a master and the second microcontroller () acts as a slave, and a second mode of inter-processor communication in which the second microcontroller () acts as a master and the first microcontroller () acts as a slave. A mode selector (-) is provided to select and switch between the first and second modes.

Vehicle safety electronic control system

A power management circuitry for a radar level gauge including a first voltage converter, having a low-voltage end for receiving a drive voltage from a power interface and a high-voltage end for supplying an intermediate voltage higher than the required operating voltage, a temporary energy store arranged to be charged by the intermediate voltage, a second voltage converter, having a high-voltage end for receiving an input voltage from the energy store, and a low-voltage end for providing the operating voltage lower than the input voltage. By storing energy at a higher voltage, a different type of energy store (e.g. low capacity capacitor) may be used. As a consequence, the cost and start-up time of the energy store is significantly reduced.
