To enhance the cold start performance of diesel vehicles integrated with Passive Entry Passive Start PEPS systems,enabling seamless entry and ignition with a direction command,a comprehensive study was undertaken on a 2.5-liter light-duty diesel vehicle.The comparison between direct start and a start after a preheating wait was performed at different test locations to validate the cold start performance.The results indicated that the direct start method was ineffective in initiating the vehicle's operation in high-altitude,low-temperature conditions,whereas employing a preheating wait prior to starting ensured successful ignition.Furthermore,in standard environments with moderate temperatures,initiating the vehicle after a preheating wait proved to be more expeditious than the direct start method.
