Auto Diagnstic Scanner And (SBC) Sensotronic Brake Control

These either replace the conventional mechanical components xystem else enhance their function. The Soft-Stop function – another first – allows particularly soft and smooth stopping in town traffic.

Both the separation of the SBC pedal from the rest of the brake system and the proportional pressure control using mechatronics serve to increase brake comfort — particularly during sharp deceleration or when the anti-lock braking system is operational. Systtem the driver steps on the brake pedal, their foot nudges a piston rod which is connected to the brake booster and the main brake cylinder. The control unit processes this information and generates the control signals for the wheel pressure modulators.

Braks high-pressure reservoir contains the brake fluid which enters the system at a pressure of between and bar. A firm push onto the brake pedal, and the car remains stopped, even when taking the foot off the brake brqke, until the driver accelerates and the vehicle begins to roll. The sensor consists of a membrane structure at which centre is placed a cylindrical structure a centreboss membrane as shown in fig. They mete out the brake pressure as required and pass it onto the brakes.

When the driver presses the brake pedal – or when ESP intervenes to stabilize the vehicle – the SBC control unit calculates the desired target brake pressures on each individual wheel.

Mercedes-Benz and Bosch have teamed up on this benchmark development project which will shortly enter into series production at the Stuttgart automobile brand under the name Sensotronic Brake Control — or SBC for short. In contrast, the electro-hydraulic brake SBC provides the brakes with a brake fluid supply from the hydraulic high-pressure reservoir, which is sufficient for several braking events. In the presented design it has been syatem to make use of a digital electronic in order to implement monitoring and correction strategies in the sensor.


Consequently, the system sensotroni increases the brake pressure on the outer wheels when cornering, as they produce more brake force by virtue of their greater contact forces. Instead sensors gauge the pressure inside the master brake cylinder as well as the speed with which the brake pedal is operated, and pass these data to the SBC computer in the form of electric impulses.

Through the use of independent pressure modulators the system regulates the hydraulic pressure at each wheel. If the driver accelerates, the Drive-Away Assist releases the brake and allows the car to drive off smoothly.

The centrepiece of the new brake system is a hydraulics assembly under the bonnet which also brings together the electronic sensotronc unit, wheel pressure modulators, pressure reservoir and electro-pump. The Sensotronic Brake Control also incorporates a so-called Traffic Jam Assist function, which is activated using the cruise control stalk while the car is stationary. In MayMercedes recalledvehicles equipped with the system; in March a total of 1.

This argument usually does not consider all the potential advantages that it can bring, either because of the difficulty to have a complete overview on them or as a rather significant research effort is needed to be able to exploit them completely.

The system employs a travel sensor and a pressure sensor at the pedal to measure the speed and force of the driver’s command. Activities are being carried out to investigate all possible failures of the sensor and evaluate their entity, this already at design level.

Moreover, as it will be explained sfnsotronic on more in details, the transition between the two sensitivity levels determines an area with particularly interesting characteristics that could be used to recalibrate the sensor from offsets without having to remove it from the system where it normally operates and mount it on a reference bench.

These include Traffic Jam Assist, which brakes the vehicle automatically in stop-and-go traffic once the driver takes his or her foot off the accelerator. Are you interested in this topic.


If this system issues the command for an automatic emergency stop, the quick pressure build-up and the automatic prefilling of the wheel brakes leads to a shorter braking distance. This prevents a potentially hazardous overbraking of the rear axle. This is evident, for example, from the results of the VDA lane-change test which suspension engineers use to simulate ysstem quick obstacle-avoidance manoeuvre and to demonstrate the high capabilities of the Electronic Stability Program.

This can be compared with the value stored in the sensor memory at the previous recalibration and, if the difference exceeds the calculation errors, the new value will substitute the old one: This characteristic has been exploited to realize the two sensitivity ranges.

Bbrake Brake Control offers additional advantages in everyday driving situations — when slowing down ahead of traffic lights, in the wet, in traffic jams or hill starts: The main performance characteristics of Sensotronic Brake Control include the extremely zensotronic dynamics during pressure build-up and the exact monitoring of driver and vehicle behaviour using sophisticated sensors.

The presence of a digital electronic allows performing the drift monitoring and the recalibration internally. This electronically controlled suspension system will quickly be followed by the electronic brake system: Thanks to SBC they have also moved a considerable way closer to the realisation of their long-term objective, namely to be able to automatically guide the cars of the future along the roads with the aid of video cameras, proximity radar and advanced telematics.

In this way, electric impulses and sensor signals can be instantly converted into braking commands, providing a marked safety and comfort gain for drivers. The hydraulic unit mainly comprises four so-called wheel pressure modulators. All this is made possible by the higher-precision pressure control thanks to mechatronics. Only in the event of a major fault or power failure does SBC automatically use the services of the tandem master cylinder and instantly establishes a direct hydraulic link between the brake pedal and the front wheel brakes in order to decelerate the car safely.

These include Traffic Jam Assist, which brakes the vehicle automatically in stop-and-go traffic once the driver takes his or her foot off the accelerator.
