ELECTRO-HYDRAULIC BRAKING SYSTEMS |
摘要 |
A vehicle electro-hydraulic braking system having a fluid pressure accumulator of the pre-charged diaphragm type which is used to store fluid under pressure, charged by means of a fluid pump or compressor driven either by an electric motor or direcly from the vehicle engine for supply to a valve system which is adapted to supply the brake or brakes of the vehicle with fluid pressure in accordance with the level of the driver's braking demand, the control of the accumulator pressure being arranged to lie within a fixed control range, with a cut-in pressure defining the lower limiting pressure of the control range and a cut-out pressure defining the upper limiting pressure of the control range, and there being a warning pressure range defined between a warning pressure level and the cut-in pressure, wherein at least one of the warning, cut-in and cut-out pressure levels is arranged to be controlled in dependence upon temperature.
