Abstract
A controller for a hybrid electric vehicle executes an engine starting process including a first starting process and a second starting process. The first starting process drives a motor generator. The second starting process is executed when a shifting condition is satisfied in the first starting process. The second starting process includes suspending the supply of power to the motor generator and then driving the motor generator. When an engine rotation speed becomes greater than or equal to an engine rotation speed threshold value and an elapsed time is within a second time threshold value during the second starting process, the controller determines that an engine is successfully started. The second time threshold value is greater than a first time threshold value that is compared with the elapsed time during the first starting process.
