Abstract: A brake fluid pressure controlling unit for a vehicle includes a metal fluid pressure controlling block, a cover, a circuit board, an electronic component, and an electric conductor. The metal fluid pressure controlling block is electrically connected with a body of the vehicle. The cover is fixed to the fluid pressure controlling block. The circuit board is received inside the cover, wherein an electronic control unit is mounted on the circuit board. The electronic component is assembled to the fluid pressure controlling block. The electric conductor is connected with a grounded portion of the circuit board in the cover, the grounded portion being grounded, wherein the electric conductor electrically connects the fluid pressure controlling block with the grounded portion of the circuit board.

Abstract: A wheel speed sensor assembly includes a rotor formed with first and second protrusions arranged circumferentially on the outer periphery thereof in two separate rows at an equal angular pitch. The first protrusions are angularly displaced from the respective second protrusions by half the angular pitch of the first or second protrusions. The sensor assembly further includes a senor having two magnetoelectric devices each opposing the first protrusions or second protrusions. With this arrangement, the differential waveform produced by the sensor has a flat stepped portion between any adjacent rising and falling portions of the differential waveform. The flat portions make the rising and falling portions steeper and shorter. Thus, when the sensor vibrates in the rotational direction of the rotor, the differential waveform is less likely to overshoot the upper threshold or undershoot the lower threshold, which in turn prevents abnormal block pulses from being produced.

Abstract: An electric parking brake control unit of an electric parking brake apparatus has an input section for receiving signals for performing automatic activation and deactivation, but does not have a determination function and a circuit for inputting signals from various sensors, which are necessary to determine whether to start the automatic activation/deactivation control. Therefore, when used in a vehicle which does not require an automatic control function and requires only a manual control function, the electric parking brake control unit can be used solely, with no signal line connected to the input section. When used in a vehicle which requires both the automatic control function and the manual control function, the input section is connected to a second control unit that can output signals for performing automatic activation and deactivation, whereby the electric parking brake control unit operates in cooperation with the second control unit.

Abstract: A heat dissipation device is disclosed for dissipating the heat produced by electronic components (16) of an electronic control device. The electronic control device includes a circuit board (14), a resin protective case (10), and a metal actuator block (20). The electronic components are mounted on the circuit board. The protective case confines the circuit board within a thermally restrictive environment. The actuator block is mounted to the outside of the protective case. The heat dissipation device includes a heat conduction path (24, 30) that serves to thermally conduct the heat produced by the electronic components from the interior of the protective case to the actuator block.

Abstract: A heat dissipation device for dissipating heat produced by electronic components of an electronic control device is disclosed. The electronic control device includes a circuit board and a protective case. The electronic components are mounted on the circuit board. The case substantially confines the circuit board. The heat dissipation device includes heat conductive terminals. The heat conductive terminals are connected to the circuit board in positions proximate to the respective electronic components, so that the heat of the electronic components is transferred or conducted to the heat conductive terminals. The heat conductive terminals are connected to the case body in order to further conduct the heat to the case body.

Abstract: A controlling device for automatic speed change mechanism is disclosed in which acceleration efficiency and fuel economy are simultaneously achieved. The device of the present invention is constructed such that plural sets of predetermined speed change programs are provided for indicating the relationship among the increase of driving power, that is, the opening degree of the throttle valve, the speed of the automobile and the speed change step. Based on the selected program information, the controlling of the speed change is carried out, while automobile height detection devices are provided for emitting electric signals corresponding to the distance between the surface of the road and the body of the automobile. Based on the height of the automobile body detected by the automobile height detecting device, a switch-over to a proper speed change program is carried out.
