HYBRID SPORTSCAR Bosch technology onboard the new Maserati Ghibli Hybrid
Maserati has chosen Bosch as its technology partner for its first electrified model. The new Ghibli Hybrid will feature Bosch components and technologies for hybridisation, safety and comfort.
Bosch is supplying the key components for the hybridisation of the new Maserati Ghibli, the first hybrid car of the Modena-based sports car manufacturer. The Stuttgart company's technology package contributes to increased performance and reducing CO2 emissions by recovering deceleration energy and optimising the use of the electric motor to support the thermal engine.
The synergistic performance of the two drive systems is coordinated by the ECU engine control unit, which among other things helps to reduce emissions from the combustion engine. The 48 V DC/DC converter converts the electrical energy from 48 V to 12 V, thus making it possible to supply the vehicle's other electrical consumers. It also ensures optimum efficiency to avoid energy losses. The 48 V lithium-ion battery is the central electrical component of 48 V hybrid drive systems. A conventional car loses energy every time the driver brakes. Still, the Boost Recuperation System (BRS) stores part of this braking force in the 48 V battery and releases it when the driver accelerates. In this way, less fuel consumption results, reducing the amount of CO2 in the exhaust and lowering fuel consumption.
Expertise in 48 V technology
Bosch has been producing 48 V batteries at its Wuxi plant in China since 2018. Since then, some 100,000 batteries made, and from 2022 the production lines will be increased from two to four. Bosch forecasts that by 2025 almost 20 % of the new cars sold worldwide each year will be equipped with a 48 V system and a suitable battery. The company's goal is to integrate this technology into all vehicle classes to meet future emission requirements and offer affordable hybridisation. To this end, the Bosch portfolio for 48 V hybrid vehicles includes highly efficient and compact components that are adaptable to different vehicle classes.
Semi-autonomous driving available
For the new Ghibli Hybrid and the entire MY21 range, the German company has contributed the ADAS active driving assistance functions, which are available in addition to the functions already available, such as adaptive cruise control, autonomous emergency braking, lane departure warning and active Blind Spot Assist.
Active Driving Assist represents the further development of the motorway assistance system that Bosch has been supplying for the Maserati series since 2018. The latest system, which equips the new Maserati Ghibli Hybrid, combines adaptive cruise control and lane departure warning technologies to adjust the car's speed, acceleration, braking and steering. Thanks to the intelligent integration of the two technologies and the optimisation of the lateral and longitudinal lane control, Bosch technology allows semi-autonomous driving (SAE 2 level) both on straights and in curves.
The novelty of Bosch technology means that GPS signals are no longer indispensable for locating the vehicle on fast roads and can therefore no longer be activated only on motorways.
The vehicle automatically follows the vehicle in front along the route at a safe speed and distance: if the vehicle in front slows down, the system reduces the speed proportionally; if the vehicle accelerates or changes lanes, the system automatically accelerates to the speed set by the driver. Also, the system automatically accelerates to the speed set by the driver. By detecting road markings and automatically intervening in the Bosch electric power steering system, the vehicle is in the capability of maintaining the centre of the road at all times, even when cornering. Although the system supports driving in a partially autonomous way, the driver remains responsible for the vehicle and must supervise the system and, if necessary, take full control of his Maserati.
