  • Created to avoid slippage

  • Wheels will release breaks momentarily when they sense that they wheels are locking up

  • When wheels are rolling, static friction slows them down, but when they slide, friction becomes kinetic and the braking distance increases

  • Considering how the brakes ease up every time that the wheel begins to lock or slide, I don’t think it would create enough heat to do any sort of damage to coexisting internal systems

  • Current ABS systems, such as Bosch, use hydraulic presses and a control panel

  • The hydraulic presses are in charge of braking, and speed sensors are in charge of sending information relevant to see if a wheel is “locking” to the control panel

  • The control panel then determines how much pressure should be applied by the presses in order to keep the wheels from locking, and the pressure of course can be something that varies over time.

  • The control panel would fall as an electrical component

  • I am also assuming there will be a fair bit of machine learning that will be necessary to create an effective control panel

  • The mechanical aspect of the brake would be to the creation of the hydraulic presses that cause the actual braking of the wheel to happen

  • ABS is an electro-mechanical system, as the hydraulic presses are mechanical and the control panel along with the sensor are electrical components

  • This would mean that regenerative braking for this system would not take away as much power from the car as it only needs to power the sensors and the control system

  • But it also doesn’t mean it would be worth it as the actual braking mechanism (the press) is still mechanical

  • ABS braking for drum and disc are practically the same. For drum braking, the hydraulic press applies pressure to the drum using the shoe of the brake and for disc braking, the hydraulic press applies pressure to the disc using the shoe of the brake

  • There are ABS systems that are capable of fitting in smaller cars, but those are generally designed by experts within the industry (such as Bosch) and I am not sure how well we can replicate a design like that at that size

  • ABS can take up a lot of space on the car so it may not be the perfect system for this specific car

  • Hydraulic presses also require fluid to function which can also result in additional weight to the car

  • However, it may be possible to use a pneumatic press instead, although that may make it harder to maintain braking pressure
