Abstract

A vehicle control device using brake hydraulic pressure includes a hydraulic unit having a housing and an electronic control unit having a casing. The housing of the hydraulic unit is mounted on a mounting surface of the casing of the electronic control unit so that the casing of the electronic control unit protrudes from the housing of the hydraulic unit to one side. On the protruding area of the casing, a bulge is formed in which a vehicle behavioral sensor is mounted. A control connector is also provided on the protruding area of the casing. The bulge does not protrude from the substantially square contour of the vehicle control device. Thus, the bulge will scarcely increase the installation space of the vehicle control device. A vehicle behavioral sensor is mounted on a small substrate. By adjusting the angle and position of the small substrate relative to a control substrate in the casing, the position of the sensor can be adjusted relative to the travel direction, lateral direction and vertical direction of the vehicle. With the position of the sensor adjusted, the small substrate is fixed to the bulge of the casing.

Claims

1. A vehicle control device comprising:

a hydraulic unit comprising a housing and hydraulic pressure control valves mounted in said housing,

an electronic control unit for controlling said hydraulic pressure control valves, said electronic control unit including a casing having a mounting surface on which the housing of said hydraulic unit is mounted, said housing being mounted on the mounting surface so as not to protrude laterally beyond an outer periphery said mounting surface, the housing protruding perpendicularly away from the mounting surface in one direction, the casing of the electronic control unit having a protruding portion protruding from the housing of said hydraulic unit in a direction substantially parallel to the mounting surface,

a connector for said electronic control unit mounted on said protruding portion so that the connector and the housing are mounted on a common side of the casing, said protruding portion having a bulge, and

a vehicle behavioral sensor mounted in said bulge, the bulge and the connector protruding in the one direction from the protruding portion and in the one direction from a plane containing the mounting surface.

2. The vehicle control device of claim 1 wherein said connector is mounted on a portion of said protruding portion where said bulge is not formed.

3. The vehicle control device of claim 1 wherein said bulge is provided vertically downward from said connector.

4. The vehicle control device of claim 1 wherein said electronic control unit includes a control substrate mounted in said casing for controlling said hydraulic pressure control valves, said bulge being disposed between said connector and said control substrate so as not to protrude from said protruding portion.

5. The vehicle control device of claim 1 wherein said electronic control unit includes a control substrate mounted in said casing for controlling said hydraulic pressure control valves, and said sensor is mounted on a small substrate supported on said control substrate.

6. The vehicle control device of claim 5 wherein said small substrate has a first side edge thereof connected to said control substrate so as to extend transverse to said control substrate and to be inclinable relative to said control substrate, and has a second opposed side edge thereof fixed to an inner surface of said bulge.

7. The vehicle control device of claim 6 wherein said second side edge of said small substrate is fixed to said inner surface of said bulge through a spherical bearing with said small substrate inclined at a predetermined angle relative to said control substrate.

8. The vehicle control device of claim 6 wherein said second side edge of said small substrate is fixed to the inner surface of said bulge with said small substrate inclined at a predetermined angle relative to said control substrate by passing an adjusting screw through said bulge, threading said adjusting screw into said small substrate near said second side edge thereof, and fixing said adjusting screw to said bulge.

9. The vehicle control device of claim 8 wherein said adjusting screw is operable from outside said casing.

10. The vehicle control device of claim 9 wherein signals are transmitted through said connecter by multiplex transmission.

11. A vehicle control device comprising:

a hydraulic unit comprising a housing and hydraulic pressure control valves mounted in said housing,

an electronic control unit for controlling said hydraulic pressure control valves, said electronic control unit including a casing having a mounting surface on which the housing of said hydraulic unit is mounted, said housing being mounted on the mounting surface so as not to protrude laterally beyond an outer periphery said mounting surface, the housing protruding perpendicularly away from the mounting surface in one direction, the casing of the electronic control unit having a protruding portion protruding from the housing of said hydraulic unit in a direction substantially parallel to the mounting surface,

a connector for said electronic control unit mounted on said protruding portion so that the connector and the housing are mounted on a common side of the casing, said protruding portion having a bulge, and

a vehicle behavioral sensor unit mounted in said bulge, the bulge and the connector protruding in the one direction from the protruding portion and in the one direction from a plane containing the mounting surface, wherein

the vehicle behavioral sensor unit is the only element provided in the bulge such that no other element besides the vehicle behavioral sensor unit is provided in the bulge.

12. The vehicle control device of claim 11 wherein the vehicle behavioral sensor unit comprises a sensor and a sensor substrate.

13. The vehicle control device of claim 12 wherein the vehicle behavioral sensor unit further comprises an adjusting screw.

14. The vehicle control device of claim 13 wherein a side edge of the sensor substrate is fixed to the inner surface of the bulge with the sensor substrate inclined at a predetermined angle relative to a control substrate provided in the electronic control unit by threading the adjusting screw into the sensor substrate near the side edge of the sensor substrate, and fixing the adjusting screw to the bulge.

15. The vehicle control device of claim 14 wherein the adjusting screw is operable from outside the casing.

16. A vehicle control device comprising:

a hydraulic unit comprising a housing and hydraulic pressure control valves mounted in the housing,

an electronic control unit for controlling said hydraulic pressure control valves, the electronic control unit including a casing having a mounting surface on which the housing of the hydraulic unit is mounted, the casing of the electronic control unit having a protruding portion protruding from the housing of the hydraulic unit in a direction substantially parallel to the mounting surface, the protruding portion having a bulge, and

a vehicle behavioral sensor unit mounted in the bulge, the vehicle behavioral sensor unit being the only element provided in the bulge such that no other element besides the vehicle behavioral sensor unit is provided in the bulge.
