Functionality Analysis of an Automated Hill Start Assistance System using Hardware Intersection Loop
Main Article Content
Abstract
The objective of the hill start assist (HSA) feature is to aid any motorist who attempts to provide initial motion to a vehicle in uphill condition. In uphill conditions, the activated system will keep the additional required pressure in the wheel brakes for an extended period of time than the driver can with the brake pedal. As a result, the individual will be able to shift his foot from the brake pedal to the accelerator pedal. A new self-contained module which depends on electronic hydraulic operations, built around an actuator that does not require a solenoid has been designed and tested in this study. The new designed system does not impart functionality comparable to a parking brake that may be employed. The new HSA system will be activated only when the ignition system is turned on. Once the ignition key is disengaged or the clutch is completely released, the HSA device will automatically alleviate the pressure on the brakes. The hardware intersection loop simulation rig is fabricated to test the functionality and performance of the newly developed HSA system in controlled settings.
