Abstract: An arrangement for monioring multiple channel solenoid currents wherein a plurality of separately controllable solenoid coils are coupled commonly by a single current measurement element to one side of a current supply.

Abstract: An arrangement for monioring multiple channel solenoid currents wherein a plurality of separately controllable solenoid coils (10a, 10b, 10c) are coupled commonly by a single current measurement element (24) to one side of a current supply (16, 18).

Abstract: An electro-hydraulic braking system of the type capable of operating in a brake-by-wire mode wherein hydraulic pressure is applied to braking devices at the vehicle wheels in proportion to the driver's braking demand as sensed electronically at a brake pedal, wherein when it is detected that there exists within the system a prescribed category of non safety-critical fault, it is arranged that the driver is caused to experience a modified, different to usual, travel/force behaviour characteristic through the braking pedal when braking.

Abstract: A system for measuring loads in a vehicle comprising strain and/or displacement sensing elements and a local electronic interface which are adapted to be linked to a main electronic unit in a vehicle with which the load measuring system is associated. The load measuring system comprises an internal micro-controller within the interface which is adapted to receive signals from the main electronic unit to switch elements of the load measuring system into both zero setting and calibration modes. The micro-controller has electrically alterable, non-volatile memory which is adapted to store zero setting and calibration data for subsequent use in a normal operating, load measurement mode of the system.
