ELECTRONIC GEARSHIFTING
SYSTEMS (EGS)

FASTER SHIFTING & REDUCING INSTALLATION COMPLEXITY FOR SIMPLE SETUP

The Zytek EGS (Electronic Gearshift System) is the only high-level advanced gearshift system that is purely electro-mechanical, making it far superior to its mechanical counterparts.

Used in both competitive and one make series such as the A1 Grand Prix, the EGS (electronic systems) units have been used to control over 1.3 million electronic shifts a year.

Most commercially available automatic and semi-automatic electronic gear shift systems used in motor racing applications (instead of mechanical systems) are based on either hydraulic or pneumatic power sources.

The Zytek EGS has been specifically developed to avoid the installation complexity, maintenance requirements and mass associated with pneumatics or hydraulics.

The EGS is capable of individual gear shifts in 25 milliseconds, and up to 5 downshifts in less than a second, much faster than mechanical equivalents.

Additionally, the precise control of the electric actuators results in very little wear on the gear selector mechanism and dog rings, which extends gearbox life, improves the reliability, and shift accuracy of our electronic gears.

Gear ratios are set and stored in Non-Volatile memory for downshift over-rev protection of the engine.

KEY ADVANTAGES

INTELLIGENT SHIFTING &
REDUCED GEARBOX WEAR

Reduced Wear

Faster gearshift systems have reduced wear on gearboxes as a shift is only initiated at a zero torque point on the gearbox. Unlike a hydraulic and pneumatic system, where you are trying to scrape a gear along because it’s being forced to shift permanently.

There is now another direct-acting motor system on the market, but the Zytek system offers more shift force and cleaner gear shifts, so the Zytek shift system is able to offer some of the fastest power to power on shift times, offering maximum performance and gearbox control.

Intelligent Shifting

A key feature of Zyteks EGS is the automatic shift retry strategy in the event of a failed shift.

To ensure all shifts are successful the system is available with an intelligent actuator; so when the driver sends the shift request, the gearbox control unit does the intelligence work to ensure the shift is successful.

In some configurations, the unit can act as a dumb actuator and the intelligence resides on the ECU which the manufacturer controls. For example the BMW M6 GT3 was equipped with this system (Zytek still undertakes servicing and spares manufacture for those systems).

FREQUENTLY ASKED QUESTIONS

An electronic gear shift system (EGS) is a device that allows for automatic gear changes in vehicles equipped with manual transmissions. EGS systems can be either mechanical or electrohydraulic.

Our electronic gearshift system is the only high-level advanced gearshift system that is purely electro-mechanical.

Electronic shifting stores electrical energy in HV capacitors, and only discharges it to the actuators when torque has been released during an ignition cut prior to a shift.

The system can perform a single gearshift (defined as power on to power on for an upshift) in ~25milliseconds, and is capable of completing 5 shifts in less than 1 second.

Yes, the paddle-shift gearbox is available.

Yes, using one of two methods:

  1. If the engine has an electronic throttle control – a request can be transmitted over CAN.
  2. If a cable throttle is used – a throttle blipper can also be supplied.

Using complex strategies included in the EGS ECU. 

Alternatively, the EGS ECU can be used as an actuator and gearshift control strategies included in other vehicle-side controllers.
