![]() ![]() The Bosch iBooster is an electromechanical brake booster (rather than vacuum assisted) primarily found on Electric Vehicles such as Tesla, but can also be found on other vehicles including ones with an Internal Combustion Engine. Surprisingly, the cost is near enough to a wash between the two. The iBooster is able to run in a fail-safe standalone mode with no other connections or communication to additional components needed besides voltage supply and chassis ground as the iBooster has an internal Pedal Travel Sensor that is externally wired to the iBooster ECU. Has anyone here used a Bosch iBooster for their build I’m planning out my braking system and - since I my old brake booster is shot - I’m wrestling with whether I should go with a vacuum based system (booster, tank, pump, etc) or experiment with an iBooster. Therefore the iBooster is an ideal component for many applications such as electric vehicle conversions (rather than using a vacuum pump), classic cars / muscle cars / hot rods (typically with manual brakes), limited vacuum pressure (such as diesel or turbo engines), or clearance issues of engine swaps (like the BMW E30 with a S54 engine).īosch iBooster Gen-1 Connector Kit Contents: The information from the Pedal Travel Sensor is used by the iBooster ECU to drive the electric motor which provides additional force towards the Master Cylinder. dose any one have any extras or even the full gen1 ibooster harness for reference heres the part numbers i found. 5x – Pins for 0.50 – 0.75mm² wire and Seals for 1.4 – 2.1mm insulation diameter ( 1 spare, see recommended wire).ġ0x – Small Pins for 0.35 – 0.50mm² wire and Seals for 1.2 – 1.6mm insulation diameter (4x for CAN-Bus*, 1 spare, see recommended wire).2x – Medium Pins for 1.50 – 2.50mm² wire and Seals for 2.0 – 2.7mm insulation diameter (1 spare, see recommended wire) Bosch iBooster Gen-2 Connector Kit Contents: 10x Small Pins for 0.35 0.50mm² wire and Seals for 1.2 1.6mm insulation diameter (4x for CAN-Bus, 1 spare, see recommended wire) To our knowledge CAN-Bus integration and custom tuning of the iBooster has not been achieved yet but we opted to include the additional pins and seals if.3x – Large Pins for 2.50 – 4.00mm² wire and Seals for 3.4 – 3.7mm insulation diameter (1 spare, see recommended wire). ![]() * To our knowledge CAN-Bus integration and custom tuning of the iBooster has not been achieved yet but we opted to include the additional pins and seals if you wish to experiment or if this becomes viable in the future. Network Functional development and customer interface for ESP Gen 9 / iBooster Gen1: Porsche & Bentley Goals. – There are two versions of the Bosch iBooster Gen-1 and Gen-2. With the iBooster, Bosch has developed a vacuum-independent, electromechanical brake booster that meets the demands of a modern braking system. Be sure to order the correct kit based on the style of Pedal Travel Sensor Connector, and use the correct wiring pinout. highly dynamic A fast pressure build-up enables short stopping distances for automatic emergency braking and covers future NCAP requirements. Instead it relies solely on the pedal position sensor for input. In retrofit application none of those elements are present and all of the programming in the ECU is bypassed. Production of the new iBooster will start in 2013.– All items within this connector kit are genuine items sourced from authorized distributors. racer17 said: In the stock application the iBooster is controlled via the CAN bus and the master cylinder feeds fluid through an ABS pump. The booster unit is purely electromechanical, without brake fluid, which means it can be rotated flexibly about the longitudinal axis. For example, if a vehicle offers different driving modes such as sport, comfort, or economy, the brakes can be made to react more softly or more aggressively as appropriate. The iBooster allows developers to define characteristic braking curves in order to adapt the pedal feel to a customer’s wishes. The iBooster incorporates a motor to control the degree of brake boosting via a two-stage gear unit for situation-dependent support on demand, avoiding the costly process of generating a vacuum using either the ICE or a vacuum pump. If the brakes are applied harder, the iBooster generates the additional braking pressure needed in the traditional way, using the brake master cylinder. The Bosch iBooster recovers almost all the energy lost in typical braking operations by ensuring deceleration rates of up to 0.3 g are achieved using the electric motor alone. Ideally, a vehicle would be slowed down purely by the electric motor, avoiding the loss of valuable energy through braking. ![]() Posted Jby Charles Morris & filed under Newswire, The Tech.īosch has developed a new electromechanical brake booster called the iBooster, which is designed to make hybrid and electric vehicles more efficient by providing situation-dependent support when a driver initiates braking.įor maximum efficiency, a hybrid or EV must recover as much energy as possible when braking.
