What is ABS on motorcycle
With the development of two wheeler industry, the motorcycle technology is more and more mature, the motorcycle displacement becomes larger, riders driving faster and faster, the motorcycle brake system is directly related to the driver’s life safety, whether it is a large-displacement or small-displacement motorcycle, the ABS antilocking system has become the standard products of various manufacturers.
Riders may not normally use, but in critical moments may be able to save your life, which is the importance of the ABS system, many riders in the purchase of motorcycle configurations, the concept of ABS is still not very familiar with the article will be about some of the doubts about the ABS to give you popularization ……..

1. What is ABS
1.1 Definition of ABS
Motorcycle Antilocking Brake System, referred to as motorcycle ABS, it is one of the motorcycle parts. Its principle is the same as the car’s, in the braking process, the wheel speed sensor constantly the speed of each wheel speed signals in time to the ABS electronic control unit, the ABS electronic control unit according to the set logic of the control of both the speed sensor input signal processing.
The ABS electronic control unit processes the input signals from the two speed sensors according to the set control logic, calculates the reference speed of the motorcycle, the speed of the front and rear wheels and the deceleration, and determines the slip rate of each wheel.
Through the cyclic control of pressure rise, pressure hold and pressure reduction of the front and rear wheels, the slip rate of each wheel is kept within the ideal range, preventing the wheels from completely locking up, so as to improve the braking effect and safety.
1.2 ABS's function on a motorcycle
The function of ABS is to automatically control the size of brake force when the motorcycle is braked, so that the wheels are not held dead and are in the state of rolling and sliding.The main role of ABS:
- Improve the anti-skid ability, to avoid tire locking
- Improve the stability and maneuverability of the vehicle when braking
- Improve the service life of tires
- Shorten the braking distance, improve braking effect
- Reduce driver fatigue
1.3 Purpose of ABS
The purpose of ABS is to ensure that the adhesion between the wheels and the ground is always the largest, so that the motorcycle can still maintain good directional stability during emergency braking to avoid loss of control of the vehicle.
2. The composition of ABS
2.1 Wheel speed sensor
Monitor the current wheel speed, and the wheel speed signal is converted into an electronic signal provided to the ECU computer for slip rate control.
2.2 Controller
Accepts signals from the speed sensor and analyzes them to calculate the vehicle speed, wheel speed, slip rate and wheel acceleration signal and deceleration signal. And analyze, discriminate and amplify these signals to control the actuator work.
2.3 ABS warning light
When the ABS system is faulty, the ECU (explore more about what is motorcycle ECU ?) controls it to light up and alarm to inform the driver of the current system fault.
3. ABS system classification
According to the channel, it can be divided into single-channel ABS and dual-channel ABS.
- Single-channel ABS: ABS anti-lock braking system is installed only on the front wheels, which can prevent the front wheels from locking, even during emergency braking.
- Dual-channel ABS: front and rear wheels are equipped with ABS, is two independent, with complementary control systems, better than single-channel ABS braking effect, braking force distribution is more balanced, to maintain the vehicle’s optimal braking status.
4. How to use ABS correctly
4.1 Braking in front, then back, front and rear
Generally speaking, motorcycle braking techniques mainly include front and rear, front and rear parallel. The usual operation of motorcycle enthusiasts is to brake before and after, which is not scientific in terms of vehicle design structure and braking characteristics.
4.2 Front brake and the rear brake
The front brake is the main, the rear brake as a supplement, even if the front brake is a little bit stronger, it is okay, because the ABS will prevent the wheels from locking phenomenon, do not have to worry about the vehicle will slide!
4.3 Reasonable use of the engine's traction power
Vehicle speed reduction can not rely solely on the brake system, the need to make reasonable use of the engine traction, as long as the two are perfectly coordinated, the vehicle speed reduction will be more efficient!
Brake ratio is generally:
Front Brake: 50%, Rear Brake: 30%, Engine: 20%.
Conclusion
To summarize, having an ABS on motorcycle is one of the motorcycle safety tips and it plays a vital role in emergency braking and greatly improves the safety of the rider. By preventing the wheels from locking up, ABS ensures the motorcycle’s directional controllability during braking and avoids serious accidents that may occur due to loss of control. However, one thing that must be noted is that more electronic devices are auxiliary, the main thing is still people, safe driving, is a necessity.
FAQs
How can ABS be triggered?
Routine operation is sufficient: ABS will be triggered when the wheel lock condition reaches the preset value when braking the brakes vigorously.
Special conditions: for stunt vehicles can cause wheel locking phenomenon of non-braking operations, may trigger the ABS, then you need to turn off the ABS function and then perform, otherwise it will affect the driver's operation.
Why is it difficult to trigger ABS on my motorcycle??
1. Different road surfaces:
due to the design of the vehicle, the wheel locking point is relatively large, even if not equipped with ABS, on dry cement road, the brake pinch will not lead to wheel locking, so it is difficult to trigger the ABS on high adhesion road, the smaller the road adhesion, the easier it is to trigger the ABS. For example, it is more difficult to trigger on a concrete road, but very easy on a gravel road.
2.Human reasons: when you are operating, you don't dare to squeeze the front and rear brakes, which gives the impression that it is very difficult to trigger the ABS. This is a psychological effect. Design reasons
ABS is the last line of defense to ensure safety. Manufacturers do not want ABS to be triggered as a last resort, so it is difficult for ABS to be triggered.
Which road surfaces are prone to trigger ABS?
Low Coefficient of Adhesion: Due to the low coefficient of friction, the wheels are more likely to skid or lock up, which triggers the ABS system to intervene to maintain the stability of the wheels and the braking effect.
Rainy or snowy road surface: In rainy, snowy or slippery conditions, the wheels are prone to skid or even lose control when braking sharply due to the slippery road surface. In these cases, the ABS braking system can also effectively prevent the wheels from skidding and keep the vehicle stable during hard braking.
Can I use ABS in curves?
ABS can't be used in normal ABS vehicles, try to let the body relatively upright before braking; ABS can only be used in vehicles with cornering ABS, and the cornering ABS function is generally only assembled in some high-end models, equipped with a "tilt angle sensor" electronic control equipment.
Difference between ABS and CBS
Different functions, ABS is to prevent the brake force is too strong and lead to wheel locking, causing the vehicle skidding phenomenon, it is this feature to a certain extent to ensure that the car does not roll over; CBS has a front and rear brake linkage, but it does not have the wheel anti-lock function, so the two from the main role of the difference is still relatively obvious.
