TOYOTA has filed eight patents with america Patent and Trademark Workplace for a “pseudo handbook transmission”, replete with a clutch pedal, which is earmarked for an electrical car.
The Aichi-based agency is the newest automobile maker to experiment with an electrical car with a multi-gear transmission; patent drawings present a management unit (with three particular person modes) that adjusts the torque output of the electrical motor to supply a extra petrol-like driving expertise.
The pseudo handbook transmission goals to “present an electrical car (with the flexibility to ship) a driving feeling like an handbook transmission (MT) car with out (a driver) experiencing the difficulties (related to working an) MT car,” the patent software outlines.
The pseudo handbook transmission is mated with what the patent submitting describes as a “pseudo shifter” and “pseudo clutch pedal” – neither are important to the car’s operation, however might assist reproduce the expertise of a standard six-speed handbook gearbox for many who search it.
To additional the expertise, the shifter will even transfer just below acceleration and deceleration – simply because it does in a car with an everyday handbook ‘field – and may even simulate the impact of a automobile stalling.
“The controller of the electrical car is configured to regulate the torque of the electrical motor utilizing the MT car mannequin primarily based on the operation quantity of the accelerator pedal, the operation quantity of the pseudo clutch pedal and the shift place of the pseudo shifter utilized by the operation of the response drive actuator,” the patent software particulars.
“The controller is configured to retailer the shift response drive attribute of (and simulate the attribute in response to) the operation of the shifter. Then, the controller is configured to regulate the shift response drive output by the shift response drive generator in response to the operation of the pseudo-shifter utilizing the saved shift response drive attribute,” it continues.
With almost all EVs at the moment working with no conventional geared transmission – other than examples from Audi and Porsche – the patent submitting suggests Toyota might certainly be transferring to retain the driving fanatic shopper base that it’s labored so onerous to recapture.
Although it’s possible the transmission will initially see the sunshine of day in Toyota’s upcoming Sports activities EV, the design might certainly serve to present an electrified Yaris GR and 86 with the form of driving H-pattern expertise clients are used to – and will additionally serve to supply improved towing, hauling and off-road capabilities within the model’s in depth vary of four-wheel-drive fashions.
Whereas a lot of the patent describes – at size – how the system works, the notes across the powertrain management module’s programming and switching between “computerized” and “handbook” modes are positive to be of most curiosity to three-pedal drivers.
In response to the patent software, the a number of modes supplied by the pseudo handbook will be programmed to go well with totally different driving kinds or certainly totally different drivers, catering to drivers who benefit from the engagement that solely a handbook transmission can present.
“Within the first operation mode, an operation quantity of a pseudo clutch pedal and a shift place of a pseudo gearshift are enter to the MT (handbook transmission) car mannequin to replicate operation of the pseudo clutch pedal and operation of the pseudo gearshift in electrical motors management,” the patent reads.
