First Claim
Patent Images
1. A brake control assembly for a vehicle brake system, the vehicle having an axis, the brake control assembly comprising:
- a hydraulic control valve body including electrically controlled components, said valve body adapted to be hydraulically connected to the vehicle wheel brakes;
an electronic control unit for controlling the valve body components, said electronic control unit mounted upon said hydraulic control valve body to define said brake control assembly;
means for mounting said brake control assembly upon the vehicle in a predetermined off axis orientation relative to the vehicle axis; and
at least one motion sensor mounted within said electronic control unit, said motion sensor being oriented within said electronic control unit to compensate for the off axis mounting of the brake control assembly upon the vehicle such that, when the brake control assembly is mounted upon the vehicle, said motion sensor will properly sense motion of the vehicle relative to the vehicle axis.

Abstract
Secondary circuit board which carries an acceleration sensor is mounted upon a primary circuit board in an anti-lock brake system control unit. The secondary circuit board is mounted at an angle to the primary circuit board and the acceleration sensor is mounted at an angle relative to the secondary circuit board to align a sensing element contained in the acceleration sensor perpendicular to a direction of vehicle travel.

16. A method for fabrication of a brake control assembly for a vehicle brake system, the vehicle having an axis, the method comprising the steps of:
-
(a) providing a brake control assembly that includes a hydraulic control valve body including electrically controlled components, the valve body adapted to be hydraulically connected to the vehicle wheel brakes, an electronic control unit for controlling the valve body components, the electronic control unit mounted upon the hydraulic control valve body to define said brake control assembly, the electronic control unit adapted to carry at least one motion sensor;
(b) determining a mounting location for the brake control assembly upon the vehicle; and
(c) orienting a motion sensor within the electronic control unit such that the mounting orientation of the brake control assembly relative to the vehicle and the mounting location of the motion sensor relative to the brake control assembly cooperate to position the motion sensor to properly sense motion of the vehicle relative to the vehicle axis. - View Dependent Claims (17, 18, 19, 20, 21, 22)
