If, for example, you’re steering sharply to the left or right, but the car is ploughing on straight ahead (perhaps because the road is very wet or icy), the computer can recognise this and instruct the car’s systems to step in and help. This computer then compares what you’re doing to how the car is responding. This umbrella includes anti-lock brakes (ABS) and traction control (TCS).Īs you steer, accelerate and brake, clever sensors monitor the car’s behaviour and send data to a central on-board computer. How does ESP work?ĮSP combines several technologies to keep the car safely on the road, in control and heading in the direction you want. The once-common initials TCS (Traction-Control System) or ASR (Antriebsschlupfregelung, ‘drive slip control’, in German) are used for wheelspin-preventing technology and were more common before being integrated into electronic stability control in most models. Some brands like to give the system their own stamp: Volvo uses the name Dynamic Stability & Traction Control (DTSC), while Porsche calls it PSM (Porsche Stability Management – not to be mixed up with PASM, which stands for Porsche Active Suspension Management and describes Porsche’s adaptive suspension system. The system is sometimes referred to as VDC (Vehicle Dynamic Control), VSA (Vehicle Stability Assist) or DSC (Dynamic Stability Control) on vehicle equipment lists. Carmakers have trademarked different names and acronyms for the system, but they all do the same job. It’s worth keeping in mind that your car could have ESP installed, but it might be named something else. What are the differences between ESC and ESP? Our guide explains why ESP is so essential in modern car safety. In Sweden alone, wet-weather collisions have reduced by 30%, thanks to ESP. So my conclusion was: electric assisted power braking using the Tesla iBooster was the best way forward in my EV conversion project.ESP (Electronic Stability Programme), also known as ESC (Electronic Stability Control), is a live-saving technology that has been mandatory on modern cars in Europe since 2014, though some older cars have it too.Ĭar dashboard warning lights: the complete guideĪccording to UK research, the chances of being involved in a fatal crash are reduced by around 25% when driving a car with ESP. It can be used in “failsafe” mode just by implementing the pedal travel sensor on the unit and powering it up.
In the video the GEN 1 iBooster is shown and used in later Model S cars with Autopilot, in the model X, Chevrolet Bolt and Malibu and the Honda CR-V. IBooster: Finally the iBooster made by Bosch.
And searching for and using 25 years old parts was not really an option. However I could not find any of the components new. In terms of weight of the car that could match quite nice. Advantage is that it is quite a stand alone system and I could even also easily implement the ABS. Lexus: First I looked into the systems used in a Lexus since they have a ‘drive by wire’ philosophy, but it turned out it would require re-using multiple components.įord: The first type Ford Scorpio (1985-1994) had an electric brake booster. My next question was: what cars have electric assisted power brakes and looked into a couple of options. The way forward was electric power brakes.
For example from ABS Powerbrakes you can buy their “ Electric High Power Electric Brake System“. Stand alone hydraulic pump, matching master cylinder and accumulator.Moving away from vacuum assisted power brakes can also be very relevant for muscle cars or hot-rods where vacuum pressure or space (or both) are limited. I definitely wanted to prevent the sound of “prrrrr” when you switch on the car and looked into alternatives. In some cases it might be a valid and low cost solution while accepting inferior braking performance and noise. In my previous post on vacuum assisted power brakes I looked into vacuum pump.
