Title:
CONTROL SYSTEM FOR STARTING ENGINE IN LOW TEMPERATURE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/029558
Kind Code:
A1
Abstract:
A control system for starting an engine in a low temperature comprises a braking heating device (10), an oil sump heating device (120), and a controller (130). The braking heating device (10) is connected to a vehicle energy storage system (200) and is used for heating cooling water in an engine cooling loop. The oil sump heating device (120) is connected to the vehicle energy storage system (200) and is used for heating engine oil of an engine. The controller (130) is connected to the vehicle energy storage system (200) and is used for controlling the vehicle energy storage system (200) to carry out electric discharge when the temperature is low and a rotation reverse-delay resistance moment is higher than a first preset value, so as to heat the braking heating device (110) and the oil sump heating device (120). The controller (130) is connected to a power generator (300), and is also used for controlling the power generator (300) to reversely delay the rotation of the engine to make the engine slowly rotate at a preset rotation speed, so that the heated cooling water and the engine oil are transmitted to devices in the engine, so that the engine is again warmed evenly. Also provided is a vehicle using the control system for starting an engine in a low temperature. The engine is again warmed evenly when the engine is cold-started, thereby improving the maneuverability and the environment adaptability of the vehicle.
