Abstract

The invention discloses a vehicle idling start and stop control system and method. The control system judges whether a vehicle has idling start and stop conditions by monitoring the water temperatureof an engine, the capacity of a storage battery, a safety belt and other information, judges whether the vehicle has conditions of stopping the engine by monitoring the rotating speed of the engine, the speed of the vehicle, the brake air pressure and other conditions, and judges whether the vehicle has conditions of starting the engine by monitoring the gear of a gearbox, the speed of the vehicle, a hand brake and other information. When the relevant conditions are met, start and stop work signals are sent to the engine though a CAN bus. In order to guarantee the reliability of frequent startand stop of the engine, the system strengthens flywheel gear rings of a starter and the engine. In order to ensure that the battery does not lose power, a storage battery capacity sensor is added tothe system on the basis of increasing the capacity of the storage battery, and the idling start and stop are allowed when the state of charge (SOC) of the storage battery satisfies a safe starting threshold. The idling start and stop control system has advantages of low cost and high reliability, and is especially suitable for commercial vehicles.

Description

technical field [0001] The invention relates to a vehicle idling start-stop control system and method, and is particularly suitable for the field of commercial vehicle control. Background technique [0002] Vehicle idling start-stop control technology is one of the core technologies of vehicle energy-saving control. Its function is to suspend engine work when waiting in line or in traffic jams, and quickly start the engine when the vehicle senses the driver's intention to start. Idle start-stop control can effectively reduce fuel consumption and reduce harmful gas emissions in urban and waiting conditions. [0003] Passenger cars currently use glass mat absorption battery AGM and smart generator solutions to overcome the risk of battery power loss caused by frequent start and stop. However, at present, there are no supporting resources for relevant parts and components in the field of commercial vehicles, and other technical methods need to be used to control the risk of ba...
