Next-generation automotive actuators deliver significant haptic improvements

18-07-2016 | TT Electronics | Design Applications

New automotive actuators for next-generation haptic accelerator pedals have been developed by TT Electronics. The actuators tackle the weak spots of systems currently available on the market, offering a sub 400 gram total weight - a significant reduction from the total weight of comparable pedals, says the company. The haptic pedal actuators enable power-efficient transmission, consuming less than 1W of energy with an active actuator when it reaches a pedal force increase of at least 10 Newtons. The pedal force the driver feels increases when the drivetrain changes from battery to combustion engine. The additional pedal force can be customised according to OEM specification. The actuator offers a high degree of reliability without long-term degradation across -40C to 80C. Offering a substantial improvement on conventional systems which can frequently fail to function after increased or long duty cycles or across wide temperature ranges. The simple, lightweight, rugged and compact actuator provides optimum design possibilities for customer-specific applications, says the company.
