HYDRAULIC HYBRID VEHICLE METHOD OF SAFE OPERATION

摘要

A hydraulic hybrid vehicle includes elements such as a hydraulic pump (104) driven by an internal combustion engine (102) and arranged to draw in low pressure fluid and pump the fluid at high pressure to an accumulator (108) hydraulic motor (110) is powered by the pressurized fluid. Safety processes are provided for detecting and addressing a number of conditions that may arise in the operation of the hydraulic hybrid vehicle, including an initialization procedure for start-up of the vehicle, a shut-down procedure, and procedures for detecting and responding to failure of the pump or motor, internal and external fluid leaks, and non-responsive actuation and mode control systems.
