摘要： A wiper apparatus using a three brush, permanent magnet motor in which a zener diode has a cathode connected to the low speed brush and an anode connected to the high speed brush. The zener breakdown voltage of the zener diode is chosen so that it reverse conducts during at least some portion of each wipe cycle during operation with the high speed brush on a wet window to limit peak wiper speeds and reduce strain on the wiper mechanism. Variations including a transistor, relay or additional zener diode controlled by the zener diode and connected in parallel therewith provide for reduced current and therefore power dissipation in the zener diode at the expense of somewhat limited speed limiting.

摘要： A system including a node, wherein the node includes two separate controllers, each of which is configured to output data to a bus, or receive data from a bus, or output data to and receive data from a bus. At least one controller is configured to monitor the output of the other controller and is configured such that if the at least one controller determines that the other controller is providing improper data or signals, at least part of the output data of the other controller is nullified, overridden or superseded by an output from the at least one controller.

摘要： In a vehicle suspension control in which the output of a vehicle body mounted absolute vertical acceleration sensor is integrated to provide an absolute vertical velocity signal, the sensor output is high pass filtered to remove DC components but pass components in the frequency range 1-2 Hz. The filter comprises a second order digital all-pass filter embodied recursively on a 16 bit, fixed point, digital signal processor (DSP). A first stage normalized lattice two-pair network reduces to a unity gain stage; and a second stage single multiplier two-pair lattice network minimizes computational time. The 32 bit internal accumulators of the 16 bit DSP are used advantageously to prevent errors due to internal overflow of the recursive variable.

摘要： Disclosed is a method for assisting the parking of a vehicle. The method includes determining a vehicle position relative to an obstacle. When the relative position meets a first set of criteria, a first torque pulse is delivered to the steering wheel in the first direction to cue an operator of the vehicle to turn the steering wheel in the first direction. When the relative position meets a second set of criteria, a second torque pulse is delivered to the steering wheel in the second direction, opposite to the first direction to cue the operator to turn the steering wheel in the second direction. A system for assisting the parking of a vehicle is also disclosed.

摘要： A vehicle window washer in which the pump outlet pressure is varied in an inverse manner with temperature of the washer fluid so as to maintain a more consistent fluid deposit on the window as fluid viscosity changes with temperature. In particular, it uses a motor driven pump which provides a higher pump outlet pressure with the motor driven in a first direction than with the motor driven in the opposite direction and switches activation of the motor between the two directions based on sensed temperature of the fluid in the washer fluid reservoir.
